It will be very usefull to have function to get logged user token.
Currrently there is arcade data function GetUser(), but user token is not provided. Only logged user name, email and other basic information.

My use case:
Want to configure arcgis popup to show hyperlink with my custom webservice and provide logged user token as parameter. Token will be used for authorization in my custom service.
