How to Save Paint/Material used in layer for use in another project (Substance 2021)

I've created a paint with specific fill properties I'm using in a fill layer (or a paint layer for that matter). 

I'd like to reuse this paint with its custom properties in another Substance project.  Is there a way to save it so it shows as a material I can then quickly access and reuse elsewhere. 

Older posts on this said to right click the fill layer and use a Save option?  -- dont see that in v2021.

How please?
