Is there a way to control the accessibility greyscale mode from terminal/script/bash or bind a hotkey to it?

With the release of Plasma 6.6, we now have the (much?) anticipated greyscale accessibility mode. I absolutely love this, as it gives me a more paperlike look for reading ebooks and generally going easy on the eyes. Many thanks to the developers!

I'm trying to figure out a way to switch it on and off on demand without having to open settings. For example, on my Android, it bound it to volume up + power button. best case scenario, I can do it from the keyboard shortcuts section of the system settings, but I'm also willing to write a script.

Any tips? Thanks in advance!
