What Part Do I Need Please To Fix

[Tim330]

A piece of door trim has come off. I think I need a push in fitting that expands when pushed in. It's a 2018 BMW gran tourer (a poor man's M3 touring). Can anyone help with what part I need?

The answer to anything BMW parts related is to look on realoem.com.

Just a standard plastic expanding rivet.

Thank you, ordered an assortment box from Ebay.
