I don't know what modules/plugins are the best neither do I have any particular preference other than if it works well and if the developer replies to the issues and is helpful. So don't take this as an endorsement.
What you're trying to use is a module, and that requires you to compile Godot from source. Godot usually compiles well but if I can avoid custom builds, I do. I've used this one ( https://github.com/cgisca/PGSGP ) in 2 of my games and had no major problems - well, I did, but they were related to Google configurations and permissions.
One important thing to note is that Godot release 3.2.2 implements a different plugin architecture and it's not compatible with the 3.2.1 modules. My implementations were all 3.2.1 so I don't know if the developer supports 3.2.2.
Take a look.
