Effecthouse BETA versions of Mac & Windows

Hi, I’m using a Mac but collaborating with a friend using Windows.
We want to use the VFX features in the Beta versions but while my Mac Effecthouse beta goes up to 4.6.1, my friend’s window Effecthouse Beta version only goes up to 4.2.5
Is there a way for her to use 4.6.1 like I do?

Also wondering if there’s a way to package files or assets while collaborating. we’ve been trying to use prefab but it doesn’t seem to bring stuff like dynamic chains. We were thinking of either using Git or taking turns updating one project file. But does anyone have a better way for collaborations?
