Im developing a web app in asp.NET core MVC, which objective is to be deployed to microsoft teams. I need to use Azure AD authentication. Azure authentication cannot be used inside an iframe, but microsoft has an available work around (https://docs.microsoft.com/en-us/microsoftteams/platform/tabs/how-to/authentication/auth-tab-aad) to authenticate users in teams tab, which I was able to implement and retrieve the access token.
My questions are:
-How do I tell to the server that a user is logged in?
-If a user is in browser, is it possible to have both teams tab and browser authentication?
Very thankful for any (really any) help!
