Fenix 6 pro solar and inReach Explore +

I just purchased a fenix pro solar.

I can't locate a widget to install inReach remote.

Is it not supported? If not, why not? I noticed the inReach mini is supported.  The Exploer + is supposed to be a more advanced version of the mini (I had thought).

I also noticed inReach Explore+ is not supported by Garmin Explore app?

Pretty disappointed I can't connect my $650 inReach Explorer + to my $1600 watch.
