Migration from Google Maps: Import Timeline from Google Maps

How to import all (now device specific) Timeline tracks from Google Maps into Osmand?

Google Timeline was not optimal as there was no configuration about how many points are tracked and how often. This is better done in the Trip Recording plugin. But it was just there and tracking all the device all the time.
Now Google changed their policy only allowing to read the timeline on the specific device. That makes it impossible to work with the timeline on other devices or browsers, which made me searching for alternatives...

I have years of Google Timeline, now only accessible on the device. It is possible to backup that Timeline to the Google Cloud in some secure way, and somehow possible to restore to a new device. But how can I get the raw data and tracks.

The only thing I know, that Google is forced to provide all user data as a big binary blob from the Account, but that would not contain the Timeline anymore afaik.
