Best Ways to Share Concepts with Clients for Feedback

Hey guys, quick question. How do you typically share concepts with your clients? I had in mind to share the link from within the style guide, specifically the "pitch concepts" link. However, I noticed that with the share link, there is no option for the client to comment, and it also gives them access to the wireframe and sitemap. Is this correct? Is there a better way to pitch concepts to a client? Do you even pitch the concepts at all, or deliver the final webflow project?
