Fenix 7X Pro + inReach Mini 2 - Sending custom message to MapShare from watch via inReach widget

Hello community, hello Garmin support,

TL;DR:

When composing a custom message on my Fenix 7X Pro via the inReach widget or data page for sending it via my inReach Mini 2, I can't select "Mapshare" from the contacs list since there is no such entry while it is available in Garmin messenger and on the Mini 2 itself.

---------------------------------------------

I would have a question regarding remote controlling an inReach Mini 2 via my Fenix 7X Pro.

With the inReach Mini 2 you can send two types of messages. The three predefined ones for checkin and custom ones including predefined templates for the latter.

For the three predefined checkin messages, you setup the recipients in Garmin Explore. So here I've setup the cellphone number of my wife and also MapShare. This ensures that all checkin messages I send also appear in MapShare on the map which is great, since you can see the messages at the location where they have been sent.

So now I want to do the very same with custom messages and here comes my problem.

When I want to compose a custom message (or use one of the predefined templates) this time I have to chose from my contacts to whom I send this message. When I do this with the Messenger app on my phone which is connected with the inReach Mini 2, or directly on the Mini 2, there is an entry "Mapshare" in my contacts list. So also for these messages I can easily send them to one or more contacts AND make them appear on Mapshare.

BUT my normal usecase is, to remote control the Mini 2 which resides in my backpack via my Fenix 7X Pro and while I see all the contacts here that I maintained for my Mini 2, I do NOT see an entry "Mapshare".

My question is, if I'm missing something in the setup process, or if I can manually add a contact which achieves this and how it has to look like, or if this is a missing feature or a bug in the Fenix firmware. I'm running the good old 17.28 FW on my Fenix since it's stable.

Any ideas?

Best regards,

Thomas
