executeDaxQueries-like API call with effectiveUserName on SSO-enabled model with Service Principal

Please provide a way for a service principal to execute DAX - with an effective user name - against an SSO-enabled directlake semantic model and get per-user results that respect lakehouse OneLake Security data access role restrictions (RLS, CLS).

This should not require granting every effective user access to the execute queries API endpoint, which creates security and governance issues.
