Capacitor Google fit plugin

I’m trying to understand how the capacitor plugin works to link my ionic app with Google fit. I’d like to know if there’s a test API on the Google side, and if the following plugin is the right one to use?
I’ve come across articles saying that this plugin is no longer functional with the version of ionic 6 and above, so I’d like to know your opinion. And to know if there is a better solution to implement what I want.

Thanks in advance
