I have been reading the source code for the template: https://www.overleaf.com/latex/templates/beamer-arrows/wmqkckggvjsd which clearly shows that path supports overlays, so you can have edges on certain slides only.
However I needed the same with
\draw and doing something like
\draw<2-> doesn't work (compile error). Do overlays not work with draw? Where do I find an exhaustive list of overlays friendly tikz commands?
