How to fill in color inside a custom closed path in XCode 13.3 - SwiftUI?

I followed the steps told in this video and made a custom drawing app.

So my question is how to fill in this closed shape with red color (autofill / manual anything would be ok)?

Any kind of leads on this would be appreciate. Thanks
