Access token update issue for account having multiple users

We are writing to raise my concern about issue zoom Access token creation/updatation for zoom accounts having multiple users
Recently we have migrated from JWT to Server-to-Server Oauth
Below are the cases and issues

  1. Can we use One App for multiple Users available in zoom account.
  2. When used same credential for All users, after some time token is expired/invalid.
  3. We have 30 Users in my Account, can we use same app credential for all users,
  4. If we can’t use same app credential then what is the option, as we can’t create more than 10 APPs in Account.

Please help us to resolve this, our clients are getting affected badly.
