I'm trying to draw a symmetrical shape in Figma. Usually the way I do this is by drawing a path, then duplicating it and flipping it horizontally. In Illustrator, I would then be able to hit Ctrl+J to join the two paths, creating a closed shape that I could then fill.
But in Figma, when I select two paths, the Vector -> Join Selection (Ctrl+J) menu option is disabled. How do I join these vectors together?
