External mumble server using FXServer

Hello, I am trying to setup a external mumble server for my server, but I can’t figure out how should I do it, I read this ( [How-to] Host FiveM’s voice chat (mumble) in another server - FiveM Resource Development & Modding / Modding Tutorials - Cfx.re Community), it does teach how to set up it using docker and grumble, but I would like to know how to do it using an fxserver. Another thing I am also creating a script for this to support ranges, etc. All of it can be done on client side right?
