role the user would be allowed to join under
- enable/disable the "Share" button based on the above permissions check

Global/Popups
- calculate the `accessType` internally based on the permissions present
- update the eligibility as the async check for permissions is finished
- fix the permissions panel background color
- partially revert the share/finish/cancel buttons behavior; it must be
one button due to StatusStackModal limitations
- fix some other minor UI issues or differences to current Figma designs
- adjust SB, add the possibility to play around with different
permission models
