What is the difference between Owner, Admin, Sales and Member?

The Owner is the workspace owner, they have access to all features and oversee the management of the workspace, including billing, subscription, and adding or removing members.

The Admin has access to all features including the ability to upgrade or downgrade members.

Those in Sales have a higher level of access to the workspace than a member, with access to basic rate data

Members are just regular users, with access to all features.
