Work with WebGL?
It work in editor, but when i build WebGL not work no errors no warnings no connecting logs
You need to use some workaround. It's no problem with this plugin, but the way unity builds WebGL.
Check this link: https://docs.unity3d.com/Manual/webgl-interactingwithbrowserscripting.html
Basically, when you build your WebGL app, inside that index.html add socketi.io client (you can use from their website). And from c# call function in the browser (make some foo() function) that will init stuff like wich events to call from javascript to c#).
Inside c# just remap functionality to use external DLL import (you don't need socket.io plugin inside unity).
Sadly I don't have an example to show as I did this for the company.
