@Matt Dillon Thanks for posting in our Q&A.
For adding a shortcut of an app, it is suggested to refer to the following link to make it.

Note: Non-Microsoft link, just for the reference.
For this issue that Webex not in the Start Menu, it seems the behavior of this app itself.
What I know is limited, let's wait someone else can share more information.
Thanks for your understanding.
