Accessibility Compliance issue with Search button.

We are integrating the PDF Embedded API into our pages. We have to be Accessibility compliant , so all the icons in the page should be readable.

While most of the icons are readable, the search icon is not readable.
Please have a look at the attached screenshot (missing-accessibility.png). This shows that the element is missing "aria-label".
While the other icons have that label and are accessible.

Can you please add the attribute to this Search icon?
