JS - Geolocation API not working on mobile even on HTTPS

I'm using Geolocation API to get the user current location and it works fine on desktop. On mobile (I'm testing on Android 10, Chrome) it doesn't ask the user for location permission, so of course I can't get what I need.

I'm developing on a local Apache web server, with HTTP. I've tried with HTTPS by exposing my localhost with Ngrok (it can returns HTTP and HTTPS both), but still not working.

That's the JS code:

var lng;
var lat;

if (navigator.geolocation) {
  navigator.geolocation.getCurrentPosition(getPosition);
}

function getPosition(position) {
  lng = position.coords.longitude;
  lat = position.coords.latitude;

  // Some other code here (does not affect the API)
}

EDIT

I have also checked my phone settings and chrome settings and they're fine. I went some other websites that uses the same API and they actually works.
