Prevent TextField zoom #672

Hi, it’s not the first time I try to make this for the iOS safari, then I found a guide on how to prevent this behavior, I tried some ways to inject the maximum viewport scale and font size with no luck, can someone help me?
according with this page doesn’t look hard to prevent this, but idk how to do https://thestateofmatter.com/2-ways-to-avoid-the-automatic-zoom-in-on-input-fields

also I couldn’t find anything on the scripts repo, so I’m asking for help here. Sorry if it’s the wrong place.
