I am building a Teams extension using the Teams Toolkit and React.
I would like to access my Teams contacts (maybe get them as an array or some other collection) and display them in my extension.
I have read somewhere that the only way to do this is through the Microsoft Graph API, and that there aren't really Teams specific contacts, but that they come from multiple places within the Microsoft 365 ecosystem and possibly elsewhere.
Is Microsoft Graph API really the ONLY way to get a list of contacts into my extension? If it's not the ONLY way, is it the best way? What are other ways to access my contacts if any?
