Custom Zoom App added for local testing is absent from Zoom desktop client on Windows

Zoom Apps

There’s a more subtle problem with the listed apps when there is a mismatch between the Zoom desktop client’s signed-in user and the host user that is running the meeting. Steps to replicate:

  1. Launch Windows Sandbox for a fresh system.
  2. Transfer and run ZoomInstallerFull.exe (the Zoom Desktop Client) in the sandbox to install version 5.17.10 (33775).
  3. In the Zoom client, click Sign in and enter your developer user credentials.
  4. Click the Apps toolbar icon and confirm that you see your added apps (for the signed-in user).
  5. In Microsoft Edge, navigate to the Zoom sign in page and sign in with another user that is part of the same account.
  6. In the Meetings section, switch to the Personal Room tab and click Start.
  7. If prompted by the web browser, allow the Zoom client to open.
  8. In the Zoom client meeting controls, click Apps to observe that no added apps are listed (for the host or the signed-in user). (This is the unexpected behavior.)
  9. Switch to the main window of the Zoom client, open the account menu, and click Sign Out.
  10. Switch back to the meeting window of the Zoom client and in the meeting controls, click Apps to observe that added apps are listed now (for the host).

We use a dedicated Zoom user for webinars that is separate from the host’s personal Zoom user, so we can’t rely on the two users involved to be the same. We’re trying to pin a private Zoom App in the user interface so that the host can quickly refer to it for guidance during a sudden meeting attendee disruption. What other ways can we make a Zoom App easy to launch for the host?
