How can I use Memoji in Cordova app on iOS

I am developing a cordova based application for iOS (Cordova iOS 5.1.1, XCode 11.3, WkWebView).

I now want to make use of the Memojis of the iOS keyboard (not the Emoji!) but I do not really know how to work with them in cordova.

Memojis on the left side of the keyboard

I found this thread here: It is about Swift but it seems the Memoji gets copied into the clipboard when pressing it and then you can use it. But I did not find any information how to handle this in cordova. I tried using the copy eventHandler but it does not fire when I press an memoji. I also searched for clipboard plugins but they only provide text support.

Any idea? Very much appreciated - thanks
