Removing Universal Switch with a Broken Home Button while on the Lock Screen? (Galaxy S6 Edge)

[Android Central Question]

I recently ran into an issue where I put my phone into Universal Switch mode. While not being the sharpest tool in the shed, I restarted it and am now stuck on the lock screen. On top of all of that, my home button isn't working. I can't go to the safe mode menu because my home button's broken, and I tried using a micro USB adapter to connect a mouse and try to log in that way, but with no luck.
