Issue description

The example code in https://docs.godotengine.org/en/latest/classes/class_javascriptobject.html#class-javascriptobject throws the following error:

Error calling constructor ArrayBuffer with args: 
Array [ 10n ]
 error: TypeError: can't convert BigInt to number

I'm guessing JavaScriptBridge has changed since 4.2.2 and the documentation hasn't been updated yet. I'd like to use the bridge, what's the best way to find out how?

Steps to reproduce
