How do I pass Paginated Report Parameters using PowerBI-JavaScript powerbi-client?

I am using dataset parameters, not dataset filters so the second link, Filters (Parameters) for RDL (Paginated) report in PowerBI-JavaScript API, will not work.  In my scope, Filters are not acceptable due to performance issues as discussed Data retrieval guidance for paginated reports - Power BI | Microsoft Docs

The first link, Passing the configured parameter using the embed token, is a horribly convoluted and limited in scope hack.  I did get it to work however:

• Testing does not work with
  • Power BI Report Builder
  • Power BI App Service
• Since it is not baked in, the workaround is not self documenting
• There is a Built-in Field for the Report, UserID (User!UserID)
  • The Token Identity username maps to this Built-in Field
• If you need the actual Report UserID you cannot use this hack
• Does Not work if there are Multiple dataset Parameters
  • Could pass a mult-value string in Identity username
    • Parse UserID on Report side
  • Doubtfully use other Identity Properties but are they mapped to Report Built-in Fields?
    • datasets
    • roles
    • customData
    • identityBlob
    • reports
• This is not an acceptable solution
