I think it's important to develop your own process for thinking about this, based on your work with clients. Sorry if that's hard news! For example, my process integrates what I know about the client's history, culture, and personality dynamic. I listen to what they tell me about themselves. Based on those factors, I choose a feedback process. Example questions: What kinds of principles do people like this value? What do those principles tell me about the feedback-collection options I should pursue? There is no single process for every client. Screenshots, Zoom calls, custom annotation apps--these are all possibilities, but I choose per-client. If you work with the same type of client over time though, you will have more of a justification to identify & stick with a single process, just IMO & good luck to you.
