Get all users across al tenants including tenant name #10578

ASP.NET CORE & Angular (single solution) .NET 5.0 v10.2.0

In the host i would like to get a list of all users across all tenants including there tenant name, so i made a private function to fill tenant names, but this gives an error, can't find tenant
