Manage Comment Access for the prototype links

I work in a service-based company, and we cater to multiple clients. Our workflow involves sharing the design prototypes directly from Figma to the client for feedback. But most of the time, the clients tend to go back to the previously approved designs (from the sidebar) to add comments to them. This in turn causes a lot of rework and delay in our workflow. And yes, we have tried hiding the sidebar while sharing the links but that is just a temporary fix for this problem. So I think that there needs to be an option to turn on/off comment access for the prototype links.
