Throttle addition for Levo Fatbike

I want to add a throttle assist (preferably thumb, not twist) to nudge my Levo Fatbike from a dead stop in less than ideal situations, due to my aging, weak, and creaky legs. Has anyone done this, or know a real expert on modern small motors? I'm a retired engineer, but I know my limitations. Are electrical schematics of the Levo systems available anywhere? This should not be a difficult undertaking, because cheap Ebikes have a throttle assist to augment the pedal assist.
Thank you,
