Open TeamViewer QuickSupport App from my app in iOS

Hi, I am developing an app for iOS and I want to open the TeamViewer QuickSupport app with a button. Is this possible via an URL scheme and "openURL"?

Like this: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:"teamviewer://"]];

I know I can open the iTunes page with this URL: "itms://itunes.apple.com/de/app/teamviewer-quicksupport/idxxxxxxxxx"

But I rather want to open the TeamViewer app directly and open the iTunes page only if TeamViewer is not yet installed.
