Interactive elements indicate their purpose and state
This is an issue with Webflow, as there is no HTML native button, and you must add ARIA to Webflow "button" elements when clicking the element does something. (Remember, Links go somewhere.)
Google Lighthouse says
Interactive elements, such as links and buttons, should indicate their state and be distinguishable from non-interactive elements. To check that interactive elements indicate their purpose and state, use both a visual and a screen reader test.
