Guest is no longer a separate role. Accounts that used to be Guests now have the Client role, so this page describes what a Client can do.
FuturnFlow has four system roles: Owner, Admin, Member, and Client. An old Guest account is treated as a Client. If an admin wants someone to have a different level of access, they pick a different company role for that person.
See the Client guide for the approval steps. If you need more access, ask the person who invited you or an Owner or Admin.
