How to get all articles by author role?

Question

Laravel

Hello!
The Post and User models are in a one-to-many relationship.
There are Roles: admin, user, manager (laratrust).
How can I get all Post entries by author role like user and manager?
Something like:

Post::whereHas('user', function($query) {
                $query->hasRole(['user', 'manager']);
            })
            ->paginate(10);

This code results in an error:

"Call to undefined method Illuminate\Database\Query\Builder::hasRole()"

Thank you for your attention! :)

Post::whereHas('user', function($query) {
                $query->whereRoleIs(['user', 'manager']);
            })
            ->paginate(10);
