Sequelize self-referencing table/model not going recursive

Question

Lets suppose I have the following table in my RDBMS called "family":

id	ancestor_id	family_member
1	null	great-great-grandfather
2	1	great-grandfather
3	2	grandfather
4	3	father
5	4	son
6	5	grandson

"id" is the primary key and an auto-increment field, "ancestor_id" is a foreign key witch references it's own table, in other words, "ancestor_id" is a foreign key of "family", target column "id". A table that references itself, right? So far, nothing new. To better illustrate the example, I've added a varchar column, "family_member", it will come in handy latter as one visualizes the intend.

I'm using Sequelize as my ORM solution. I'm not a beginner in it, nor am I a beginner in ORM technology. I was using Hibernate before annotations were a thing, and before JPA started encapsulating it (some 17 years ago).

How should I configure the Model and put my query together, in order for Sequelize to give me the following object, as I query for family member id=6 (the grandson):

{
    id: 6,
    ancestor_id: 5,
    family_member: "grandson"
    ancestor: {
        id: 5,
        ancestor_id: 4,
        family_member: "son"
        ancestor: {
            id: 4,
            ancestor_id: 3,
            family_member: "father"
            ancestor: {
                id: 3,
                ancestor_id: 2,
                family_member: "grandfather"
                ancestor: {
                    id: 2,
                    ancestor_id: 1,
                    family_member: "great-grandfather"
                    ancestor: {
                        id: 1,
                        ancestor_id: null,
                        family_member: "great-great-grandfather"
                    }
                }
            }
        }
    }
}

No matter what I do, Sequelize doesn't go "recursive" on that one, all that I can get is one level deep, if I query for the "grandson" and ask to include the Model itself in the query, it will only return me the "son", and nothing above that.

What I need for this one is for Sequelize to go on until it finds a null "ancestor_id", as you can see in my JSON example.

Thanks for the time and patience.
