Trim clips are cheap, check for all the broken ones you can find and replace them. Double sided tape and some packaging materials like foam helps with rattles if stuff just doesn’t fit perfectly, if stuff is already off it doesn’t take much extra time to stick a few pads.

(If the manufacturer charges too much for clips, you can probably find them on AliExpress using the part numbers, they’re often a bit annoying to substitute so if you’re only saving a few dollars by trying your luck with a mix of generic ones, I’d say don’t bother. If you don’t have any, plastic levers for trim are also very useful and cost very little, the metal ones tend to scuff things and covering the ends in tape makes them too bulky)
