在Laravel中的刀片中添加Where子句

I am trying to add the following Where clause in a blade in laravel, but not working :

       @if( Auth::user()->grpusers()
       ->where('group_id', $group->id)->first() == True) 
       ->where('join_request', 1)->first() == True) // boolean

I'm also not sure if the boolean syntax is correct. If I remove the boolean line it works fine.
