Other Zoom accounts get "Application Not Found" when trying to authenticate with my General App in development mode.

Hi Zoom Support,

  We are building a third-party integration using a
  General App with User-managed OAuth (authorization code
   flow). Our use case: an end user authenticates with
  Zoom and we fetch their meetings (scheduled +
  completed), recordings, and transcripts.

  We have the following questions:

  1. In development mode, users from other Zoom accounts
  get "Application Not Found" when trying to
  authenticate. Is this expected? Is there any way to
  allow external accounts to test without going through
  the full review process?

  2. Is production mode (publishing to Marketplace)
  required for OAuth to work across different Zoom
  accounts?

  3. Does publishing to production require going through
  Zoom's app review/verification process? Or is there a
  way to activate the app for production use without a
  full public Marketplace listing?

  4. If verification is required — what is the typical
  turnaround time?

  5. Is there an account-level / internal app option
  where a customer can create their own General App
  within their own Zoom account, and their own users can
  authenticate without any Zoom review?

  Our required scopes (all user-level, no admin):
  - meeting:read:list_meetings
  - meeting:read:meeting
  - meeting:read:summary
  - cloud_recording:read:list_user_recordings
  - cloud_recording:read:list_recording_files
  - cloud_recording:read:meeting_transcript

  Thank you
