By the way, one other option would be to use a smart bulb in each of the three lights (assuming they’re all lights I’m not sure what the middle switch is used for) and then put a separate battery operated three toggle switch next to your existing switch. You would then put switch locks on your existing switch to keep people from turning that power off.
The three toggle switch is battery operated so you don’t have to worry about the wiring. And you can position it anywhere on the wall that you want to. But it only works if there is some network device that is actually controlling the load to the light. But that could be a smart bulb.
That might not be the aesthetic look you wanted but it is an option to consider.
