Thanks Sheena,
Nothing changed, so I'm thinking I must just be looking in the wrong place in the Creative Cloud app perhaps; or maybe we are on completely different pages and not talking about the same thing. So let me try to clarify what I need and where I should be looking, because it sounds from your answers, like there is a simple solution to my issue, but I just cannot see what your are referring to at all.
So, what I was asking is, if the bruses that come native to Fresco can be exported for use in Photoshop. Your response implies that the Fresco Brushes are somehow in the Creative Cloud app. The only brushes I can find in the Creative Cloud app are a couple freebies that I once downloaded from Adobe Stock. As far as I can tell, the Fresco brushes exist only in Fresco. I see that you can import brushes into Fresco but I cannot see any way to export brushes out of Fresco, and I can see no evidence of brushes in my Creative Cloud app.
Would you please direct me to which part of the desktop Creative Cloud app I should be looking to find the brushes you say are managed via Creative Cloud please?

Hi Zeinat06.
Sheena is correct, the default brushes in Fresco can only be used in Fresco. But, my colleague just messaged Kyle and he said this:
The closest brush to Fresco's Pastel Square would probably be the Pastella in the Megapack Drawing Box.
Hope that helps.
Sue.
