osTicket: (v1.17)
OAuth2 plugin: 0.6
OS: Windows Server 2019 Standard
IIS: 10.0.17763.1
PHP: 8.1.11
Error:

Info:
Nothing is listed in PHP Error Log, IIS Error Log, or osTicket error log to indicate why the OAuth2 connection is invalid. Here are screenshots from our Azure portal. We're running out of ideas here, any assistance is greatly appreciated!
Note - Unable to add: POP.ACCESSAsUser.All because it is disabled by our organization for all email boxes, is this strictly required for this to function?
Note - We do not have an option for Implicit grant and hybrid flows, so cannot check Access Tokens and ID tokens as the guide states. Again, required to function?
