there is no easy hard wire fix. smart bulbs would be the easiest. put an alexa in there and turn it on and off that way. you could also buy one of the "add on" remotes for ceiling fans and light fixtures to the light fixture wiring. then you could mount the remote to the wall and use it to turn the light on and off. that just requires wiring it into the top of the light fixture.

but smart bulbs would be my go to. i use them everywhere anyways.
