If it was me I would replace a bent crank arm. Hopefully the pedal axle is not bent also. I don’t think you could get the shape of the crank arm back to factory spec. It might feel weird.

The crankshaft through the motor is usually robust but the shaft bearings could be compromised. Check that out.

A crank arm removal tool might be necessary (looks like a Bosch motor).

Sorted now with the tyre lever. I put a dent in the swinging arm so it now measures the same as the other side🤣
Regarding pedals, they are Sam hill oil slick that were on offer for £20 a pair 👍

Glad you got it sorted.
I assume the crank arms are alloy. You may only have a few bends left before they snap. ie; a bent aluminum derailer hangar can be realigned once or twice before it breaks.

Alloy can be a funny material.

Although the op was taking the piss, the tyre lever against the bottom shock mounting and a bit of careful force, bent it back the 5mm that was causing my heal to catch the upper rear triangle..

I know the OP has fixed his problem, but I would have removed the crank arm and then used a vice to squeeze the crank arm. Insert blocks as appropriate to apply the force where required. Slow and easy!
