How to transform a figure into a line in Figma?

Question

Figma

Hello everyone, if I draw any shape with a line, I can turn this line into a fill with the keyboard shortcut Ctrl
+ Shift + O If you just remove the fill from the shape and put a stroke, then the stroke turns out to be double, but I need something that looks like a fill but at the same time there is a stroke.

Answer 1

Delete the shapes that create empty space inside the shapes and turn on the stroke.
