Garmin vivofit jr

Hello all, i have made some step trackers for our family but my kid only have a vivofit jr 3. watch to measure steps, and not a phone to track step and import into HA app.

i have a hard time to try get those step data out if even possible?
i tried Garmin connect integration but seem that it only take “main account”
and garmin connect jr. uses main account to create a sub account for each kid you have.

but as far i see i cant see those data in my own garmin connect app and therefor not export with normal integration.

anyone had luck try export step out from that watch.

im fully aware that it sync manually with bt. but rigth now i cant find those data anywhere else than kids app or watch it self.

any ideas are very welcome, its just one watch we need to do.
