How set two association in sequilize in just one object

I'm using sequelize and I'm looking for the associations from the table, currently the relationship is hasMany - belongTo, BUT I would like to get the two associations in a single object

currently it's coming like this

"user": {
    "id": 1,
    "association1": [
        {
            "value": 133,
            "association2": {
                "name": "test",
            }
        }
    ]
}

Cause I wish it came this way

"user": {
    "id": 1,
    "association1": [
        {
            "value": 133,
            "name": "test",
        }
    ]
}
