Hello. The pictured recessed fixture decided to drop slightly out of the ceiling. It might have been held in previously with a paint film (I cleaned up the paint edge a bit before taking the photos), but is not tight to the ceiling currently. Are there clips that I can reset/tighten on this? How do I take it apart? I would think the trim piece would pull down or pop off but I can't get it to move--the whole can just floats around in the ceiling. Thanks.
