Ionic 4: Prevent backbutton from closing page

Hi,

I’m searching for a way to disable the hardware back button on certain pages, i.e. on a “loading” page; I know about the existence of

this.platform.backButton.subscribe(() => {
  // do something here
});

, but this allows only for performing an action once the back button is pressed, but I don’t see how to cancel the “nav.pop()” action. Do you know how to achieve this?
