In case you'd like to prevent employees from interacting and using AttendanceBot, deactivating is simple:
1) Open the settings panel by typing "Settings" as a direct message to AttendanceBot and click on the link prompted.
2) Once you open the dashboard, please head to people --> personnel tab --> find the employee using search or scroll
3) Click the "Inactive" toggle present on the right of the profile tile
NOTE: by default AttendanceBot hides already inactive employees, but this can be changed using the toggle at the top.
These employees wont be able to use the app then.
