Parallels 18.3.0 (Apple Silicon): Right Click in Guest (macOS 13.4) not working

Hi,

I have an MBP Pro with M2 Pro as a Host and Parallels 18.3.0 running.
I have setup a macOS 13.4 guest system which is - almost - running fine.

One thing not working - quite annoying: Right Mouse Click (using the MBP's trackpad) doesn't work properly:
Sometimes it works but that's more luck than anyhow reproducible.
Most times I have to to the right click gesture (two finger on the trackpad but really click - not only tip) and move the fingers a bit. Then the e.g. context menu appears. Mostly I have to keep one finger pressed down and then I can - more or less - navigate through the menu. Mostly - when I release all fingers, the menu disappears again.

Will there be a solution in the (near) future.

Also I would appreciate, when the know issue with iCloud login could be resolved
And of course: Config of the VM would be great. The default 6GB RAM seem to be a limit, as e.g. MS Teams is not working in the guest system. I hope, that this is an issue of too few RAM ;-) I have tried to modify the RAM by using the config.ini (described in the Knowledge Base), but it had no effect.

Thx & Cheers
Christian
