message: Fix missing URI escape for the PBI workspace name
diff: // - Users with UPNs in the same tenant (not B2B) can replace the tenant name with 'myorg'
  // - B2B users must specify their organization UPN in tenant name
  // var homeTenant = CurrentAuthentication?.Account.GetTenantProfiles().SingleOrDefault((t) => t.IsHomeTenant);
  - var tenantName = "myorg";
