Accessibility issue with callouts

An accessibility checker (https://wave.webaim.org/) is picking up an issue with Beaver Builder callouts on our sites which use Font Awesome fonts for their icons. The icon is considered an empty link because it contains no text, which is an accessibility problem. I guess it could be considered slightly alleviated by the fact that the icon link is immediately followed by a text link, but I’m not sure if that’s sufficient. Any suggestions for how we can fix this accessibility issue on our sites?
