Like query in laravel using multiple user id

I have chat rooms in my laravel project, my table (chat_rooms) has 2 columns user_id_1 and user_id_2and my users table has name column, I need to execute query with like search on name of user not the user who sent the request but my problem is the column user_id_1 probably is auth user_id_2 column the same. I need to search on name of user not logged in How to write this query.

this is first relation on chat_rooms model:

public function user_1() { return $this->belongsTo(User::class, 'user_id_1'); }

and this is second relation:

public function user_2() { return $this->belongsTo(User::class, 'user_id_2'); }

Thank you,
