No share screen icon on my Zoom for chromebook PWA

[larryfeltonj]

I have a problem that I can't find answered by searching the discussions here, although some of the discussions seem close.

I'm pretty new to chromebook, and am having two problems with Zoom for Chromebooks PWA.

First, each time I use it I have to access it via the Google Pay icon.  I can't find a way to install it as a default.

Second, no share icon shows up in my meetings view, even though I went to my Zoom admin panels and turned on what I assumed were the toggles allowing screen share.

I'm sure some of this is just my newness to chromebook and the Zoom PWA.  But it's driving me nuts, and I've been going around in circles in the documentation.
