import favorites

Is your feature request related to a problem? Please describe.
I export some favorites (single ponts) in Maps (e.g. 2024-02-05 16_05_55 (+01_00) filtered-favorites.gpx).
Now I want to import these favorites in a new nextcloud instance. I didn't find any option to import these file.
Other files are shown directly in the app (e.g. GPS-tracks).

The favorites are stored like these file:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<gpx version="1.1" creator="Nextcloud Maps 1.3.1" xmlns="http://www.topografix.com/GPX/1/1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd">
  <metadata>
    <name>favourites</name>
  </metadata>
  <wpt lat="51.3559473" lon="7.4734477365678">
   <name>NAME</name>
   <time>2023-12-30T15:34:38Z</time>
   <type>Personal List</type>
   <desc></desc>
  </wpt>
</gpx>

Describe the solution you'd like
Possibility to import favorites.

Start by comparing how Maps currently handles GPS-track GPX files with the exported favorites GPX example in the issue. Done means a new Nextcloud Maps instance can import waypoint favorites while retaining their names, coordinates, times, types, and descriptions; verify this with a representative file.
