Accessibility and Modern Player Previous and Next Buttons

When background changes (to the modern player) are necessary and desired for a project (instead of light or dark) the next and previous buttons are not ADA color contrast compliant. Is there any way to change the colors on the built-in "next" or "previous" buttons to meet the WCAG minimum standard contrast compliance necessary for accessibility?  

We are required to use the modern player but I cannot find a way to make the contrast on the next and previous buttons acceptable to meet the minimum WCAG (AA) contrast compliance. 

I use the Colour Contrast Analyser (CCA) to test.

Thanks
