Where you see it
Only inside the hosted flow, when it finishes adding a charger. The link session then doesn’t give your integration access to that charger.What it means
One integration controls a charger at a time (charger:control: start and stop, current limit, smart charging). Your user’s charger is controlled by another app, your user chose to keep it there, and Plugchoice set up your integration as one that only works with control. held_by.name says which app has it.
