Doesn’t work as expected

I thought I found a plugin that addresses ARIA compliance for my project but it doesn’t work based on what the description says. In WP menu screen, I can see the Aria label field for each menu item. So I put in some text there for testing. When I few the site on the frontend, I’m not seeing any Aria tag for the test menu link in the code. The link shows the ‘title’ tag with my test text. I expect the see the Aria tag instead to make accessibility compliance. This is the only thing this plugin does and it’s not working that way.
