You can set up different logins for each user with different access privileges for different areas of the interface.
To add a new user, please visit the Settings section (at the top right from your snapshot page). Select 'Team management' and there will be an 'Add a new user' button.
You can then enter a name, an email address and select which access privileges you want that user to have via the 'Job function' and 'Role.' You can reach about each Role in this Help Center article.
Once submitted, new account details will be sent to the relevant person along with a link with instructions on how they can set a password.
