I have <a> tag in my code that has tooltip attached to it and tooltips are supposed to be read by aria-describedby. Voiceover on mac is just ignoring it and only announcing the link.

I have taken this code from wcag where they assign aria-describedby to a link.

I am struggling to make the div with aria-label accessible.
