Slides Layouts for Non-Designers

As I designer, I’m pitching to my company about the benefits of using Figma Slides instead of PPT. I created layouts with column breakdowns so folks can easily snap elements to pre-set 2 col, 3 col, 4 col. But when I turned off design mode, I realize non-designers don’t have access to this. They don’t have access to X,Y coordinates or width/height adjusters so it doesn’t seem to solve the problem of non-designers creating misaligned slides, unless I build out a bunch of components to block them from making mistakes.
