Link a deck card in maps app

Thank you for this great app :-)
Our team need one function very much:

It would be great if you can add a deck or better, a deck card as a marker in the maps app.
So you can quickly jump from the linked card on the map, to the deck app to the concerned deck and vise versa.
When you hover a link in the map it would be nice to see at least the card name, deck name or the possibility to show it easily.

Optional it would be nice to see even the first or more attachement photos on the map, that are attached to the card in the deck app.

Optional it would be nice if you can enable/disable the shown cards by the filters and or tags from the deck app.

Optional it would be nice you can link favorites of the maps app directly in the menu of editing a card in the deck app or quick select a position from jumping to the maps app or show a litte segment with a cursor to select it :-)

Optional it would be nice to have a little icon in a card in the deck app when it is already linked to a position in the maps app that, when you hover it, shows a little map segment with the position in sattelite view :-)

Optional it would be nice to edit a deck card directly from within the maps app, e.g. quickly add a tag or add a notice/comment.

Yes, I dont know how much work that is, but I think a lot. Maybe enough people find it interesting.
Thanks for the whole Nextcloud project!

The issue names no files, tests, or entry points. First define which requested map-card capability is in scope and inspect how Deck currently integrates with the maps app. Done requires an agreed subset with navigation behavior and any display, filtering, or attachment requirements specified and tested.
