My iPhone 12 is not giving me the option to use the telephoto lens

I’ve been watching tutorials on how to use optical vs digital zoom to improve the quality of my photos. However, every tutorial says that when I open my camera app on my iPhone 12 (not pro), that in the Photo mode it will show me three options at once: .5x, 1x, and 3x. My camera does not show me those options. It shows 1x. When I tap it, it automatically zooms out to .5x. If I try holding it, it expands to show a wheel of zoom options, but those are all digital zoom. How do I guarantee the use of optical zoom with the telephoto lens if I don’t have the same options other iPhone users have. Is it an issue with the phone itself?
