How check if there exists a date in an aggregate query with Mongoose?

Question

I am working on a location based game an have an addressmodel like this:

const AddressSchema = new Schema({
    address: String,
    city: String,
    postal_code: String,
    country: String,
    user_id: String,
    postalCodeMeters: Number,
    date: Date
});

And the following query, which extracts some data for each postal code. This query works nicely:

await AddressModel.aggregate([
                    {
                        $match: {
                            user_id: req.params.userid,
                        },
                    },
                    {
                        $group: {
                            _id: '$postal_code',
                            meters: {
                                $sum: '$postalCodeMeters',
                            },
                            count: {
                                $sum: 1,
                            },
                            address: {
                                $addToSet: '$address',
                            },
                        },
                    },
                    {
                        $project: {
                            _id: 0,
                            postal_code: '$_id',
                            count: 1,
                            meters: 1,
                            uniqueAddressesVisited: {
                                $size: '$address',
                            },
                        },
                    },
                ]);

My problem is that I am trying to add another field to return, called "isVisitedToday", which checks if the player has visited that postal code today? How would I go about doing that? I was thinking of using startOfDay and endOfday from date-fns, so I need a way of checking if there exists any date between those parameters for each postal code.
