You're (probably) supposed to use some JavaScript on your page so that
when the user activates your toggle, you perform a request through that
web socket. A handler installed to listen on that websocket in your Go
server should parse the request sent from the browser and act
accordingly.
The best course of action is to break this task into subtasks and have
them solved one-by-one:
* Make sure activating your toggle calls whatever JS code you intend.
For this, use plain console.log("whatever") and see whether it works
in your browser's developer window. Note that contemporary browsers
even allow you to execute your JS handlers step-by-step and set
breakpoints.
* Make sure your JS handler performs the request through the web socket.
Again, this can be checked in the browser's developer window.
It allows you to inspect the request's properties.
* Make sure your Go handler works.
Match that what you install on the Go side with what you've inspected
using the browser's developer tools.
