There is no option to do this in the media library. I am using an image gallery, and under settings they provide field inputs for "Title" and "Description". According to their knowledge base, the "Description" is the "Alt text". First of all those are two different things and its frustrating that they mix terms, and second of all the Alt tag is still empty in chrome dev tools.
How do I properly add the Alt text to images used in a gallery in Wix so that I can actually verify Google can read them?
