Sharable Public Link

Our public clients are requesting a sharable version of the iTwin that contractors and other internal client users can access without requiring adding individual emails to a project. If they need to sign in or create a Bentley account, I don't see that as an issue. It would be easier to create a link and have them share it in their respective organizations rather than our iTwin manager collect email addresses to invite everyone. It would also be nice if the link set a configurable default role new users would fall under. Or add a the possibility to share the iTwin publicly with no sign in required.
