Make sure users can only access and use features of the app based on the roles and responsibilities they have.

• Show responsibilities connected to people's roles
• Only let Administrators access Group settings (should already be working through webview)
• Let people with add members responsibility access the invite page
• Let people with the remove members remove members
• Let people with the remove content responsibility moderate content

As I'm picking through this, noting:

• The figma has no mobile screens or designs, as a consequence...
• "Show responsibilities connected to people's roles" has no easily interpretable outcome.

Everything else should be straight-forward from a UI/UX perspective.
