Has anyone tried authenticating with an access token (using -AadAccessToken or -MsAccessToken)? The old version of New-CsOnlineSession had an -OAuthAccessToken param, which accepted a jwt with the PS permissions in the scope, which one could obtain silently, and so avoid login.
New-CsOnlineSession has been dropped and the SfB Connector is end of life in July and Connect-MicrosoftTeams does appear to support token for the telephony functions.
