Which filters are accessible in vtkSMSessionProxyManager

Hello dear Paraview developers!

I cant get access to my proxy via this

pxm->GetProxies(“filters_prototypes”, “MyFilter”, render_view_proxies);

Because when filter is created in pqObjectBuilder::createFilter
It does not seem to be registerd in vtkSMSessionProxyManager

When the filter is registered and how to get access to this proxy?

Best regards!
