Wallbox added energy total is missing

I have a Wallbox integration for EV vehicle. I see a sensor: sensor.wallbox_portal_added_energy. It will be reset when you start a new charge cycle. I am missing a total added energy sensor. It should never be cleared. Like that of a energy metering in a household.

This is important for a statistics graph card with stat type ‘change’ for an overview of months/years.
