Google page speed insights is saying:
Links do not have a discernible name
Link text (and alternate text for images, when used as links) that is discernible, unique, and focusable improves the navigation experience for screen reader users.
The search icon is in the class “x-btn-navbar-search” which appears to be within the theme itself. I don’t see where this can be given a name or customized. Any idea how to address this?
