Open Automator and create a new Quick action.
Set the Quick Action to No input from Contacts
From the Utilities group, drag the Run AppleScript action into the build pane (right side).
Paste in this script:
tell application "Contacts"
set thePeople to selection
repeat with aPerson in thePeople
set createDate to (creation date of aPerson)
set modDate to (modification date of aPerson)
display dialog name of aPerson & return & id of aPerson & return & "Created: " & short date string of createDate & return & "Modified: " & short date string of modDate
end repeat
end tell
Save the Quick Action with a short, descriptive name.
Open Contacts, select a contact (or many), and select your Quick Action name from Contacts menu > Services menu.
You can add a keyboard shortcut in the Keyboard System Settings. In keyboard shortcuts, select Services, then open the General section and find your Quick Action. Double-click (none) and type a shortcut.
I could have it select the file, I think, but this should show you all the info you need.
