Search for “Hexamethyldisiloxane adhesive remover”. It’s designed for removing ostomy bags but it will remove pretty much any gummy sticky glue from anything with very little effort.

I don’t know if this something you’re deliberately trying to avoid. Apologies if you are, and I’ve missed the point, but

I gave up on doing anything in TK years ago. For all the effort to make stuff work in it, you might as well just use flask and have a HTML frontend. That way, you know it’s going to work on everything and includes remote access as a bonus.

Edit: for a lot more power with a little bit more learning curve, look at fastapi.
