How to share unfinished project and continue edit? + sync problem?

Hi,

I've edited a video what's still unfinished and I want to share this unfinished project to my friend, that they can continue editing in Premiere Rush. I doubt that my Premiere Rush isn't syncing files correctly to Creative Cloud, because when I go to Creative Cloud Files, there is only the original video clips, that I added to project – and the whole unfinished project itself isn't there?

So my main questions are:

How can I share this whole unfinished Premiere Rush video project to my friend, that they can continue editing it?

Thank you!!
