Guest Mode behavior for logged-in users after Marketplace publish

Hi,

I am building a Zoom App for interpreter notifications in meetings. Before submitting for Marketplace review, I want to confirm the exact behavior of Guest Mode for my use case.

My use case:

  • I (the interpreter) am the only one who installs and opens the Zoom App
  • I use sendAppInvitation() to invite all participants
  • All participants are logged in to Zoom with their own organization accounts (e.g., company Zoom accounts), but they have NOT installed my app
  • All participants are on PC (Windows or Mac desktop client)
  • Participants include both internal (same organization) and external (different organization) users

My questions:

  1. After my app is published on the Marketplace, if a logged-in participant (from the same organization or a different organization) who has NOT installed my app receives a sendAppInvitation(), can they open the app in Guest Mode with just one click — WITHOUT being required to install the app?

  2. Is the behavior different for participants from the same organization vs. a different organization?

  3. Is there anything the participant’s IT admin needs to configure on their end to allow this?

The reason I’m asking is that I found a 2022 forum post (guest-mode-beta-not-working-for-logged-in-users) where logged-in users were being taken through the normal install flow instead of Guest Mode. I understand this was fixed in v5.11.0, but I want to confirm the current behavior before investing time in the Marketplace review process.

Thank you.
