Team Membership - Registration Team

We have these groups in wafer-debconf:

Permission	Regular Users	Registration	Registration Admin
Register	✔️	✔️	✔️
Edit own registration	✔️	✔️	✔️
Access Front Desk Interface		✔️	✔️
Check-in attendees		✔️	✔️
Change check-ins		✔️	✔️
Change food		✔️	✔️
Change accommodation		✔️	✔️
Change registration details		✔️	✔️
View all invoices		✔️	✔️
Change invoices		✔️	✔️
Collect cash		✔️	✔️
Access registration CSV exports		✔️	✔️
Admin check-ins			✔️
Admin users			✔️

Some of the above require "staff" powers too (django admin access), but I think that is mostly limited to the last 2 items.

Who needs what permissions? Do we need to grant any extra permissions to any of these groups?
