What are the requirements for a sketch layout for layout?

Question

Sketch

Question for layout designers: when working with a layout in zeplin or avocode, what requirements would you have for a layout? It is clear that you need to name and group layers, the question is how? I group everything according to the logic "less in more", every at least 2 connected logical elements - into a group. But is it always convenient for layout - to walk through nesting by 5-6 levels? I myself am not familiar with zeplin.
