Customize the pdf menu style

[defaultp2el1ukb78zr]

Is there a way to change the PDF embed menu style? For example its a light color now, and I'd like to turn on "dark mode" for the top menu. Dark background color and light text color. Ive tried adding custmm CSS to my site but it doesnt work.

Im using the Full window embed mode.

Thnaks!

At this time, customizing the UI is not a feature of Embed API.
