Ionic5 - slides not in ionic-angular anymore?

Porting ionic3 -> ionic5 app over. Where is the slides class defined?
I had something like this in my ionic3 code:

@ViewChild(Slides) slides: Slides;

where I could use slides properties to determine which slide is currently active this.slides.getActiveIndex() etc. This is gone / missing in the docs?

Found it’s called IonSlides now
