Multiple columns on Many2Many relationship

[akayumeru]

Hello, I need feature in Laravel Eloquent Relationship. I wanna be able to make m2m relationship of the same model. For example:
I have a pivot table which contains two columns: issuer and friend. With User::with("contacts")->get() I want to get eager loaded relationship where user's id exists in issuer or friend column. SQL query like this: SELECT * FROM `contacts` WHERE `issuer` = 1 OR `friend` = 1. So, I tried to use this:

return $this
      ->belongsToMany(User::class, "contacts", "issuer", "friend", "id", "id")
      ->orWhere("friend", $this->id);

But it doesn't work in eager loading. I tried to found solution within 2 months and there are no results.
