Embedded paginated report with PowerBI dataset

So it ends up looking like this and is working for now showing the reports. I should say I dont create the report or do the Power BI admin stuff, so there may be settings which now cause me to leave out the identity.

I did try using dynamic binding with this but it seems the token request always needs the datasetId used when creating the report. If I supply both (original and one I want to use) it seems to work but I only tested that against a dataset copy, needs more work to know if it is binding to correct dataset.

 var reports = new List<GenerateTokenRequestV2Report>() { new GenerateTokenRequestV2Report(report.Id) };
 var datasets = new List<GenerateTokenRequestV2Dataset>() { new GenerateTokenRequestV2Dataset(datasetId, XmlaPermissions.ReadOnly) };
 var workspaces = new List<GenerateTokenRequestV2TargetWorkspace>() { new GenerateTokenRequestV2TargetWorkspace(groupId) };
                
 var tokenRequest = new GenerateTokenRequestV2(datasets, reports, workspaces, null);
 var embedToken = client.EmbedToken.GenerateToken(tokenRequest);

 return embedToken;
