OT: Do ErgoMechMice exist?

I know this is offtopic and will probably get removed but i figured that since there are r/ergomechkeyboards that surely there need to be something similar for mice.

I am a gamer and for gaming, you can't substitute a good mouse. Sadly there aren't many ergonomic gaming mice so i am currently playing with a Logitech MX Vertical.

I found the HandshoeMouse and a bunch of other generic chinesium ergo mice but nothing really good.

Any Ideas?
