How to get related data through an intermediary?

Question

Laravel

I need to get all users with their requests and comments (see screenshot). How to register the connection in this case?
Comment Model

class Comment extends Model
{
    use HasFactory;
    public function subcategory(){
        return $this->hasMany(Comment::class, 'parent_id');
    }
}

Ticket model

class Ticket extends Model
{
    use HasFactory;
    public function user()
    {
        return $this->belongsTo(User::class);
    }
    public function department()
    {
        return $this->belongsTo(Department::class);
    }
}

Model User

class User extends Authenticatable
{
    use HasApiTokens, HasFactory, Notifiable;
    public function ticket()
    {
        return $this->hasMany(Ticket::class);
    }
}

Answer 1

If you get all user comments - add user_id to comments and hasMany to User.
If tickets with User::with('tickets.comments') and hasmany comments in ticket
