We have a SharePoint list that tracks staff members that have access to a particular website. The PowerApp contains a Person field that pulls from AD. As you type, the staff members appear in the choice list. We would like to Filter out those staff members that already have access granted to the website. We have been struggling with the correct syntax. Can anyone help with this?
"User SP List" has a column "staff". Only show those staff members that are not already in the the column "staff".
