ALM & MS Teams Integration

I am in the early stages of integrating ALM and Teams, but the Azure team is asking if ALM requires Delegated Access or App-Only Access.  Can anyone answer this question? I reached out to a support engineer at MF/OT, but they didn't know. I am using ALM 24.1

Access scenarios

The method that an app uses to authenticate with the Microsoft identity platform depends on how you want the app to access the data. This access can be in one of two ways as illustrated in the following image.

  • Delegated access, an app acting on behalf of a signed-in user.
  • App-only access, an app acting with its own identity.

Thanks
