I had an idea to create an application that supports both user and administrator, below details.
1 - Create a sheet called users that contains their personal data and with the option of active or inactive for admin
2 - Create a screen called profile and under the user data create a button called administer
3 - This button will only be visible if the user has the administrator option set to active.
4 - This button calls other screens that will be used to make changes, inclusions and etc.
I hope at least I have given a starting point
I don’t speak English so I used Google Translate
