Feature Idea: Document and/or Implement MS GCC High Support

[sharpmm]

Summary

The plugin currently implies standard MS O365 Teams support. Some tenants may need to integrate between an MM instance and GCC High Teams.

As implemented it is currently not known if this is plausible as part of the MS Graph integrations.

How important this is to me and why

Importance: High

In mixed use environments Engineers like MM, "Standard Users" like Teams they should be able to commingle even if the services are in GCC High Tenant.

Additional context/similar features

When integrating to Teams via MS Graph either add in language that says it is supported and/or any misc adjustments that may be needed to do so succesfully.
