How to export activities to a file (GPX,...) on Bounce 2?

I have bought the expensive Bounce 2 for my daughter to provide safety during her training in the forest.

Unfortunately, I did not find a way to extract her activities into a file like GPX, neither from Garmin Junior App nor from the watch USB connection. This is a huge limitation. If a kids wants to train AND have safety, he still need 2 watches apparently, so if the watch does not provide the feature of a very basic sportwatch, it becomes not better than a smartphone as another eal sportwatch need to be connected.

Is this possible to provide this very basic and universal feature or give me a trick to export her activities into files?
