Shared-Edits Improvements

Sure totally open to add a setting for “groups that are allowed to start shared edits” default to “staff” but allow you to change it to whatever you want.

This has come up for us and would be super helpful.

Would a PR be useful for this? Official Plugin PRs are pretty challenging for hacks like me as they require more setup and expertise that I have readily at hand!
