iOS - detect URI scheme links/problem with window.open() - detecting it

[PepaZapletal]

Hi,

I'm trying to detect a click on the URI scheme link button.

Please look at the screenshot below. On the web is for example a button "Navigovat" and after click it will open in a new browser tab maps URL "https://mapy.com/cs/zakladni?x=17.381604794179054&y=50.118149273062926%2C"

The button with the phone icon should open the phone dial.

On Android, I'm using "requestInterceptor" and it's working. I can detect the click.

But it's not working on iOS.

Can you help me with that?

EDIT: this is code from web:

      // MAPY.CZ
      let x = uvg.getUvgValue('%U.A.sour_2WGS_tecka%')
      let y = uvg.getUvgValue('%U.A.sour_1WGS_tecka%')
      let navigationMapy = window.open(
        'https://mapy.cz/zakladni?x=' +
          x +
          '&y=' +
          y +
          '%2C&z=17&source=coor&id=' +
          x +
          '%2C' +
          y,
        '_blank'
      )
      if (navigationMapy === null) {
        blockingWindowsAlert()
      } else {
        navigationMapy.focus()
      }

Is the code correct?
