Aftier iOS >= 12, There is only way to toggle to fullscreen through native API in Safari.

    if (document.webkitFullscreenElement) {
      document.webkitCancelFullScreen();
    } else {
      const el = document.documentElement;
      el.webkitRequestFullscreen(Element.ALLOW_KEYBOARD_INPUT);
    }
