Why do you do that?
Just get out, open the charge flap and plug the charger in.
If it's a DC fast charger, activate the charge session via the associated app or tap your RFID card.
The charging will start.
If an AC charger, it will probably start automatically but if it's a commercial one you will have to start it via the app or RFID card.
Very occasionally you may have to manually start the charge session in the car. Look at the main infotainment screen on the charging panel.
If it says "start" then you can tap that and it should kick off the charging session. That's also the spot you can stop a charging session if you want to.
After charging has commenced you can lock the car and leave it.
After a while you will be confident enough to just follow the normal process and not worry that it will start
