Mapshare live tracking using phone connection

The documentation is extremely unclear on whether it is possible to share real-time location with Mapshare (say using 10 minutes tracking) with an InReach Mini 2 or Messenger without incurring a satellite message transmission cost (on a Safety plan) if the InReach device is paired to a phone running the Explore app and the phone has an active internet connection.

Said differently, can I use the safety plan, but do location tracking via the phone so I don't pay per tracking point (as long as I have cell coverage) ?
