In my IT request application, there are two approvers: one is the Head of Department (DataCardValue9), and the second is the Admin Department (DataCardValue10).
I need to display only 7 users (O365 Email) in the Head of Department (DataCardValue9) and 2 users (O365 Email) in the Admin Department (DataCardValue10).

I have used this code to filter emails.
Filter(Choices(['CHEC IT Facility Request'.'Head of Department'),Email in ("email1@outlook.com, email2@outlook.com...., email7@outlook.com"))
But in this code, some emails do not appear in the list, and searching does not work. please help me to fix this
