Ionic 4 beta image pinch zoom

hi, in ionic 3 i used ion-scroll to to zoom in on images. i’ve slides and want to be able to zoom in on each image. is there any other way in beta 4?
thanks

Just if anybody stumbles upon this like I did:
I could not get it to work either but I am using https://ionicframework.com/docs/native/photo-viewer now.
Instead of pinching I am binding the photo-viewer to a click event and do the pinching in the opened photo-viewer afterwards.

This is working only for images though!

I’m using PhotoSwipe as Photoviewer.
It has advantage of watching multiple images in slider along with pinch zoom.
