Material icon variable font

I can see a Material font in my Figma app by default, but it doesn’t see to be the variable font version. 

I downloaded and installed the variable font version of the Google Material Icon, but I can’t seem to get it on the Figma app.

I don’t see any controls to modify the weight, grade and optical size of the font in the Typography details or variable section.

How do I get the variable font version of Google Material Icon in Figma?
