Chrome on iPhone and iPad only exposes the search engines available in Chrome's iOS settings.

1. Open Chrome and tap the three-dot menu.
2. Scroll to Settings.
3. Tap Search Engine.
4. If Queye appears, select it.

If Queye is not listed, Chrome on iOS does not currently offer a manual custom search URL field. Your best fallback is to bookmark https://queye.co/ or add it to your Home Screen from Safari.
