Chrome Remote Desktop with external mouse?

I’ve been googling for hours and all I can find are a few years old pages saying the only way to do a right click is double touch on the screen…

Has anyone found any better solution since? Maybe with External Keyboard Helper or some similar app??

Also, there seems to be no way to scroll. I’ve tried the browser version on Android tablet, and it works faster and you can scroll, but there is absolutely no way to press a right click.

It seems imposible that google would not adress this issue for years, since it’s really frustrating.
