How to use SendCustomNetworkEvent

I am using U#.

How do I use SendCustomNetworkEvent?
I have this:
behaviour.SendCustomNetworkEvent(VRC.Udon.Common.Interfaces.NetworkEventTarget.All, "woop")

Now what does this do? Do I have to have a woop method in the script that’s called from behaviour?

Yes you need that method somewhere in the script

But for Udon# related support please go to the UdonSharp discord

And the UdonSharp discord is?

It’s at the bottom of the Github page
