Using old mouse buttons as stackmat?

[EverythingCube]

Hi, I have an old mouse that I took apart in hopes of being able to turn it into a stackmat like I had seen on YouTube, but now that I have found out that Prisma Timer had a function to use both control keys to start, that seems more realistic. My question is: can I make the old mouse buttons function as ctrl keys on a mac?

This is my first post, sorry If it's in the wrong sub-forum.
