Access control feature additions

Why you want this feature / Target / Intent (Required)

Describe the feature you want Being able to make and limit a chat and other areas like message boards or specific pages that are of a person's pageskit to specific passports, both for access and visibility.

Describe the solution you'd like (Optional)

Describe the solution you want When creating a new chat, the added ability to select which passport has access - just like what is for message boards. Additionally, across the platform (all of the access control additions so far have been great but do need to be more cohesive across blocklets 😅 The above image is for a comparison of what view I'm referring to that would be nice to be consistent across the platform. The added options of visibility would also be nice in this spot, like how in the Navigation tab the visibility is able to be adjusted* except more like this edit board view over just an eyeball with a slash line.

*Speaking of the Navigation section, another place where the consistency would be a nice change.

Useful links / Additional context (Optional)

Provide us a quick idea of exactly what this feature looks like Just like the "Edit Board" style, with an added section/drop-down for "Visibility" (but with the ArcBlock blues)
