Limitation on number of Server-to-Server OAuth App

Description:
I was creating Server-to-Server OAuth apps for several purpose. After 10 or more the apps in our tenant, I cannot new one any longer and found “oauth_exceed_registration_limit”. How can I get new Server-to-Server OAuth apps?

How To Reproduce:

  1. Go to Build App, Server-to-Server OAuth app and click “Create” blue button.
  2. oauth_exceed_registration_limit should pop up in red bubble. (HTTP 429, Too Many Request)
