Can you hide output from a (not-automatically generated) join table using Sequelize.js?

I am using Feathersjs backend framework with Sequelize as ORM. Using Sequelize join tables of n:m relations can be generated 'automatically' (from hereon called 'Approach A') with the belongsToMany association, however I followed an also advocated alternative approach ('Approach B'), i.e. explicitly defining the join table with 2 belongsTo associations and using hasMany associations from the two tables you want to join to the joint table.

This works fine. However my output looks like this:

{
    "id": 1,
    "user_id": 2,
    "group_id": 1,
    "Venues": [
        {
            "id": 1,
            "capacity": "400",
            "venue_name": "Club Lotte",
            "venue_description": "Club in Rotterdam",
            "EmployeeVenues": {
                "employee_id": 1,
                "venue_id": 1
            }
        },
        {
            "id": 2,
            "capacity": "400",
            "venue_name": "Club Dino",
            "venue_description": "Club in Rotterdam",
            "EmployeeVenues": {
                "employee_id": 1,
                "venue_id": 2
            }
        }
    ]
} 

And I would like it to look like this:

{
    "id": 1,
    "user_id": 2,
    "group_id": 1,
    "Venues": [
        {
            "id": 1,
            "capacity": "400",
            "venue_name": "Club Lotte",
            "venue_description": "Club in Rotterdam"
        },
        {
            "id": 2,
            "capacity": "400",
            "venue_name": "Club Dino",
            "venue_description": "Club in Rotterdam"
        }
    ]
}

When using Approach A this exact same issue can be solved using the through: { attributes: [] } in the query. Can this also be achieved using Approach B?

Approach B uses an intermediate model and uses belongsTo. There are no features from sequelize (kind of implicated in the question) that support to leave out the output of the intermediate model (the join table). I browsed through the sequelize code and did not find 'such thing'. The instruction videos of Eric Katz (I found 3 of them on m:n with sequelize) also do not show such a method. He simply processes the output with forEach statements to get the output he wants. See at the bottom of this picture.

So in short: no such feature in sequelize for Approach B.
