What is difference between User/Admin and Guest role?

Hey Miro,

Admin has all the access of the account. Users and Guests have limited access to the account.

Admin can delete all other users and delete the account. Guest cannot perform tests on the platform.

User can see only his Test logs; however, admin can check the Test logs of all the other users in the account irrespective of their roles.
