Hi,
I'm driving a brand new 2021 E-Class S213 and I've installed a Sound upgrade in the front door. The front speaker is behind the decorative wooden door trim, which is mounted in front of the LED stripe, which generates the ambient lightning. All looks good, however, the decorative door trim starts to make some noises in the area of the front speaker when the music gets louder, as it rattles on the LED stripe. I'd like to remove the decorative door trim and add some gum between the door trim and the LED stripe in order to silence the rattling.

The decorative door trim is mounted with some squared clips in the back of the internal door cover.
Does anyone know how to open these clips?

Thanks in advance!
