Accessing Safari URL using com.apple.security.scripting-targets entitlement?

I've created an app that grabs the current URL and Title/name from the frontmost window/tab of Safari or any of a number of Chromium browsers, using NSAppleScript. The app sits in the menu bar and can be summoned by shortcut key combo.

let script = """
tell application \"Safari\"
	if not (exists front window) then return {\"\", \"\"}
	set theTab to current tab of front window
	set theURL to URL of theTab
	set theTitle to name of theTab
	return {theURL, theTitle}
end tell
"""
if let appleScript = NSAppleScript(source: script) {
	let output = appleScript.executeAndReturnError(&error)
	if output.numberOfItems == 2 {
		let url = output.atIndex(1)?.stringValue
		let title = output.atIndex(2)?.stringValue
		if let url = url, !url.isEmpty {
			return (url, title)
		}
	}
}

If I sign an archived build and run it locally it works beautifully, no matter which browser I am using.

But the URL/title grabbing breaks in sandbox due to permissions.

I read and have been informed that I need to use com.apple.security.scripting-targets entitlement. The example for this is in WWDC 2012 and talks about accessing Mail compose window.

<key>com.apple.security.scripting-targets</key>
<dict>
    <key>com.apple.mail</key>
    <array>
        <string>com.apple.mail.compose</string>
    </array>
</dict>

However, I don't want to control the app or use any access groups, as I've looked through the sdef and Safari/Chrome do not provide any access groups whose contents I'm interested in.

I just want to get the property/values of a window/tab. So I think I could be quite restrictive about the read-only access to two properties or objects that I need.

That said, I'm going back and forth with TestFlight review kind of shooting in the dark. I need help!

So I figure it's time to ask: what content should my entitlement have?

Or am I on the wrong path entirely?

I know it's possible because an app called Neptunes does it to get properties from Music.app

Many thanks in advance,
