@CNMSOSL,Thanks for posting in Q&A.
From your description, I know you got stuck in the process of TeamViewer setting.
Please check the following:
1.The administrator configuring the TeamViewer connector must have an Intune license.
2.Only a Global administrator or Intune administrator in the Intune admin center can onboard TeamViewer.
3.Use a supported Intune-managed device:
- Android device administrator (DA)
- Android Enterprise personally owned devices with a work profile (BYOD)
- iOS/iPadOS
- macOS
- Windows
4.A TeamViewer (opens TeamViewer's web site) account with the sign-in credentials.
And you can follow the link below to create the connection between Microsoft Intune and TeamViewer.
