Mack Anthem door mirror disassembly

Not sure if this is proper place to post this, if not, I apologize.

2019 Mack Anthem.

Wanted to switch CB antenna out and like a moron didn't pay attention. When I unscrewed the antenna I also unscrewed the stub between it and the mirror.

Now the piece that the stud attaches to inside the mirror body has fallen down inside the mirror body.

Looks like I need to pop off the outer (forward facing) plastic cover to reattach everything but I can't figure out how it comes off and don't want to make matters worse.

Anyone know how this comes apart? I tried Google and searching here but haven't found anything yet for this model.

Pic below is the piece I (think) I need to remove to get it all put back together properly.

 

Thanks, I pivoted the mirror all the way out and while I can't figure out how it comes off (yet) I do see a few clips along the inside like you mentioned, which makes sense now since the plastic front and rear cover appear to be snapped together somehow.

When I get some time later today I will take a closer look at getting the mirror itself off.
