Bathtub Handle with No Cap...?

[thedealman]

My bathtub handle has become quite loose. It appears as if it has a cap to allow me to access the screw, but I've tried, and it does not pop out.

I'll attach a photo. Can anyone help?

Thanks!!

Either than entire silver thing pops off, OR, there is a small hole for an allen screw on the side in the clear plastic.

The silver part with the ridges pops out. Use a sharp knife if you’re allowed to use knives.

there’s a thin oring that helps hold it in.
