        The "Login" button will appear only if silent authentication failed.

	This sample demonstrates silent authentication in a Microsoft Teams tab.
	</p>
	<p>
	The tab will try to get an id token for the user silently, validate the token and show the profile information
	decoded from the token.
	The "Login" button will appear only if silent authentication failed.
