This is the script that should work, but I can't seem to figure out what the querySelector to use:
<script>window.Squarespace.onInitialize(Y, function(){document.querySelector("????").setAttribute('aria-label', 'Instagram');});</script>
Instagram social icon on the header is missing an aria-label. Facebook and Pinterest automatically have theirs included. Does anyone have a solution to assigning that attribute via code injection? I don't seem to know what querySelector to use. Thanks!
