Bug when creating multiple render windows with VTK and WSLink

Would you also use the frontend api to add actors to views and change properties on those actors?
I manage all of those in the python side, I still use rpc calls but I use my custom ones.
As you said to manage the creation and deletion from the frontend, would you use that viewId to then manage things on the server or is there a simpler solution?
Thank you btw for your time in replying, it’s helping a lot.
