Replicated interface events / how to do otherwise

Yo
I have long tried to replicate an interface event (what I’m looking for is to find a way for the client to execute an interface message) but the option does not exist. I post this message to know how to communicate otherwise than with interfaces.
Thanks for help

Simply create a custom event called on Server that calls your interface? Or am I missing something?

I have tried this, simply doesn’t work.
