@exile360 Thanks!
About the Google's policy, I understand that the feature can no longer be part of the MW app, but, it can be released as a standalone app, just like the one that I ss/you linked here...
Looking into it, in the App Info section, the last update was on Aug 21, 2019, and the "early access program" is not available to register/download....
I would love to participate and contribute, considering the app is active and in development, but as I said, there's no information (that I know) about its state since 2019...
