[Q] autostart an app when on external power and sleep when the power is cut?

Hi experts,
Is it doable to tweak an android to autostart an app when on external power and to sleep when the power is cut?

I think of that as a dashcam application, that should autostart without manual intervention and go to sleep when the power is cut.
Just wondering if it is doable, maybe just a script?

Thank you
