Return filtered Users

Hi Guys,

A prosperous New Year to you, may Radzen be even more successful this year!

I have to filter my application users by some or other value, which happens to be an added on property.

The query builder in Radzen does not by default give a filter option for users, so there seems to be some catch. I tried adding a filter option manually but that is not working:

I started fooling around with my limited knowledge of ASP.Net and Blazor trying to add a function in the SecurityServices, with no luck so far.
....It seems as if ASPNetUsers does not support queries.

How can I filter the users?

Kind regards
Riaan
