+- name: Add macOS LoginItem using Applescript
+  description: |
+    Runs osascript on a file to create new LoginItem for current user.
+    NOTE: Will popup dialog prompting user to Allow or Deny Terminal.app to control "System Events"
+    Therefore, it can't be automated until the TCC is granted.
+    The login item launches Safari.app when user logs in, but there is a cleanup script to remove it as well.
+    In addition to the `osascript` Process Events, file modification events to
+    `/Users/*/Library/Application Support/com.apple.backgroundtaskmanagementagent/backgrounditems.btm` should be seen.
