Adding aria-required="true" to Required Form Fields in Wix Studio

Hello,

I’m working on improving the accessibility of the ‘Subscribe to our Newsletter’ form in Wix Studio. To better support screen-reader users, I want to ensure that required form fields include the aria-required="true" attribute to indicate validation requirements.

Could someone guide me on how to implement this in Wix Studio? Is there a built-in method to add ARIA attributes to form fields, or would this require custom code?
