Acceptance criteria

• In the sending map view:
  • Unless already granted, permission to access the user's location is requested when the map view opens
  • If the user's location was resolved, the map view is centered on it
  • Error handling when location resolution fails
  • Panning switches into pin drop mode
  • The location button switches back into current location mode
  • m.location->uri contains the coordinates at the center of the map
  • When in current location mode:
    • m.asset->type is set to m.self
    • zoom_level inside m.location is set to 15
    • Value of m.location->description: Element X doesn't have a UX to fill a description. So the value will be always absent/null
    • Value of m.text: the rust sdk populate this filed in the same way of the body (eg. "Location was shared at geo:42.3431550455947,13.3939963489709 as of 2023-07-03 11:15:01 +0000")
• In expanded map view:
  • When location services are active and permission has been granted, the user's own location is automatically shown
  • Default zoom level & centering (latitude: 49.843, longitude: 9.902056), zoom = 2.7
  • The location button requests and centers on the user's own location
  • TBD: Error handling when location permission is denied and user press the location button
• Analytics tracking
  • When sending a location
    • Event: Composer
    • Property: isLocation = true
    • Property: locationType = MyLocation
    • Other existing properties on the event are set according to context
    • When sending other events we set isLocation = false and leave locationType empty
