Uri (and others),
I found the similar question in a few corners of the internet and I think adding at least the additional default mouse buttons should not be all that much work. With some guidance I could probably do it myself, though the guidance would need to be quite substantial :) The mouse and the main buttons is already forwarded and that is the main part. with xev it is clear to see which buttons work on the host, but not on the guest. Anyone with some spare time (which I know is always limited for everyone), but help me where to fix this in the code and i will write a patch - or give me a good start - or start yourself. a semi working mouse in the guest is very annoying and can be one of the critical points why to use spice (or not) - at least i know it is in my case.

I'm sorry, but it is not that simple. That's the agent side. You also need the client side, and to add those buttons to the protocol (including client/server, possibly with a proper capability).
