How to force source proxy update all of its subproxies?

Hello dear Paraview developers!

Could you please explain how to force updating the source proxy’s subproxies?
I have a filter, which does what I need, and has some filters as subproxies, but it does not show me what is should with time updating.


I would not expect a filter to have subproxies tbh.

subproxies are usually used for representations.
