Description
Details on your question, workflow or the problem you’re trying to solve.
After Authorizing Zoom with zoom App, we got an Autorization code and then we removed the zoom app from Added apps. Now with grant_type=refresh_token, we are still able to get Access token. It should not generate any token, since that zoom app is removed from Added app.
With same grant_type=authorization_code, its not returning any token as expected.
We are seeing this issue for only grant_type=refresh_token.
