Lodash groupBy multiple keys & keys inside arrays

Question

I have this array below:

const products = [
    {
        isEqual: true,
        cfop: 1,
        tributes: [
            {
                tributeName: 'IPI',
                cst: 50,
                aliquot: 0.1
            },
            {
                tributeName: 'PIS',
                cst: 15,
                aliquot: null
            },
            {
                tributeName: 'ICMS',
                cst: 1,
                aliquot: null,
                orig: 'SP'
            },
            {
                tributeName: 'ICMS ST',
                mva: 10,
                aliquot: null,
            },
        ]
    },
    {
        isEqual: true,
        cfop: 1,
        tributes: [
            {
                tributeName: 'IPI',
                cst: 50,
                aliquot: 0.1
            },
            {
                tributeName: 'PIS',
                cst: 15,
                aliquot: null
            },
            {
                tributeName: 'ICMS',
                cst: 10,
                aliquot: null,
                orig: 'SP'
            },
            {
                tributeName: 'ICMS ST',
                mva: 10,
                aliquot: null,
            },
        ]
    },
    {
        isEqual: false,
        cfop: 2,
        tributes: [
            {
                tributeName: 'IPI',
                cst: 50,
                aliquot: 0.2
            },
            {
                tributeName: 'PIS',
                cst: 10,
                aliquot: null
            },
            {
                tributeName: 'ICMS',
                cst: 10,
                aliquot: null,
                orig: 'SP'
            },
            {
                tributeName: 'ICMS ST',
                mva: 10,
                aliquot: null,
            },
        ]
    }
]

I want to group the following properties if they're equal: "cfop" and "tributes.cst". But I will only compare this if "tributes.tributeName" === 'ICMS'. Maybe I should use a filter? I don't know. So the return would be:

const output = {
        1: [
            {
                isEqual: true,
                cfop: 1,
                tributes: [
                    {
                        tributeName: 'IPI',
                        cst: 50,
                        aliquot: 0.1
                    },
                    {
                        tributeName: 'PIS',
                        cst: 15,
                        aliquot: null
                    },
                    {
                        tributeName: 'ICMS',
                        cst: 1,
                        aliquot: null,
                        orig: 'SP'
                    },
                    {
                        tributeName: 'ICMS ST',
                        mva: 10,
                        aliquot: null,
                    },
                ]
            },
            {
                isEqual: true,
                cfop: 1,
                tributes: [
                    {
                        tributeName: 'IPI',
                        cst: 50,
                        aliquot: 0.1
                    },
                    {
                        tributeName: 'PIS',
                        cst: 15,
                        aliquot: null
                    },
                    {
                        tributeName: 'ICMS',
                        cst: 1,
                        aliquot: null,
                        orig: 'SP'
                    },
                    {
                        tributeName: 'ICMS ST',
                        mva: 10,
                        aliquot: null,
                    },
                ]
            },
        ],
        2: [
            {
                isEqual: false,
                cfop: 2,
                tributes: [
                    {
                        tributeName: 'IPI',
                        cst: 50,
                        aliquot: 0.2
                    },
                    {
                        tributeName: 'PIS',
                        cst: 10,
                        aliquot: null
                    },
                    {
                        tributeName: 'ICMS',
                        cst: 10,
                        aliquot: null,
                        orig: 'SP'
                    },
                    {
                        tributeName: 'ICMS ST',
                        mva: 10,
                        aliquot: null,
                    },
                ]
            }
        ]
    }

]

Tried a few things with lodash and lodash.groupBy but couldn't achieve. How can I do so? Thanks!
