Microsoft makes a very helpful Chrome and Edge plug-in that checks your site against WCAG 2.1 AA recommendations. Run it and fix the issues one by one and you're like 80% of the way there. https://accessibilityinsights.io/ https://accessibilityinsights.io/ The other 20% is often like judgment calls on navigability and readability on screen readers. You can install one (or several) and try to navigate your site and menus using them. They are often free, especially the ones built into major operating systems. If you want help, there are also website accessibility consulting firms, sometimes run or staffed by people who are blind or hard of vision. The one we used gave us an extensive audit and documents and spreadsheets full of things to address. It was largely similar to the methods I described above though, so I'd start with those first. (I'm a sighted frontend dev who's done accessibility work and audits for a few orgs, but this isn't my specialization. It just doesn't take much to do all the low hanging fruit, but most websites don't bother. Depending on your jurisdiction, it may or may not be legally required for your site, but if it only takes you a couple days... Why not?)
