Mobile Site Zoom

Wix Team -
I want to prevent the the zoom in effect on my mobile site when users select a user input. I believe traditionally we’d need to change the viewport meta tag to set maxium-scale to 1.

Is there a way to do this on wix? I tried adding the viewport meta tag and a wixMobileViewport tag in the add header codes in the SEO section of the editor but didn’t work. Can I set this somewhere else?
