Retrieving additional columns on pivot table (e.g.: updated_at on role_user)

[stavrogin]

Hi,

I have to get the last update role assignment of a user, so I have created updated_at timestamp.
When I perform a query such as
let users = (await this.model.query().with('roles').fetch()).toJSON()
when I loop on user.roles, I can see the property "pivot" which contains user_id and role_id.
How can I enrich the "pivot" by adding the updated_at timestamp column that I have added?

Thanks
