Map middle-click to paste (cmd-v) as on Linux?

Anybody know of a simple/cheap way to get the Mac to treat middle-click as paste (cmd-v) just like on many Linux/UNIX systems?

I’m aware of how to change the mappings of modifier keys on a KB and I know where I can set what a right click (“secondary click”) does, but I can’t see anything in vanilla macOS to map middle click to cmd-v. Any free little hack app out there perhaps? :wink:

Not free, but very reasonable, and has a 45 day trial:
