You can use Google Maps to get the position when the user clicks on it.

 // Configure the click listener.
  map.addListener("click", (mapsMouseEvent) => {
	console.log(mapsMouseEvent.latLng) // {let: latValue, lng: lngValue}
	// Updating input values
	latInput.value = mapsMouseEvent.latLng.lat;
	lngInput.value = mapsMouseEvent.latLng.lng;
  });
