Power BI - Using DAX, how can I check which Role (from Row Level Security) the user is using?

Hi,

I have created four Roles (Full Company, North, South East, and South West) via Row Level Security. The way this RLS will be implemented is by assinging the user email address (userprincipalname) in the Power BI Service against the Role. When a user logs in using their userprincipalname the correct Role will be assigned to the user and thus they can only see their granted data.

I would like to know if there is a way, using DAX, to check which Role name (i.e. Full Company, North, South East, or South West) is being used - what would be the DAX to achieve this?

My aim is to provide a tailored message, via a card or another visual, that will instruct the user based on the role being used. For example, is the North Role is being used when viewing the report then a message like "This North region will show you.....", or if the South East Role is being used a message like "The South East region incorporates...".  I suspect a Switch function will be require but the key thing is using DAX to check which Role is being used by the user.

Thanks in advance.
