Bypass Power BI login by passing external username to share URL (currently using dynamic RLS)

[Anonymous]

Currently we have an external application (with individual user logins) that we would like to add a link in that would take external users to the Power BI reports shared with them based on dynamic RLS.  The caveat to this is all users use the same workstation with a generic login, which is why we need to find a way to pass the username used for dynamic RLS via the share URL or another means.  The application is Java based.  Can this be accomplished?  If so, what options are available?

Thank you.
