'Ionic framework 5, iOS cordova InApp Browser does not open at runtime, no error message

I have an ionic 5 framework, cordova app, which utilises the inapp browser plugin. However when I click one of the buttons to open the inapp browser it doesn't work. There is no error either. The Angular code I believe is correct because the identical code works in Android. I can recreate it in the emulator, but there are not errors in the console either. Not sure where to look next.

   Ionic CLI                     : 6.18.0 (/usr/local/lib/node_modules/@ionic/cli)
