Trying to change the navigation bar icons (not background)

[obvious123]

Hi ,

I'm trying to make the Android navigation bar icons appear white, but no matter what I do, the navigation bar stays grey.

I started working on this because Google requires updating the app to Android API 35. On API 35, I had to adjust the navigation bar and status bar padding to fit my app screen, and now I’ve set their background colors. Next, I need to ensure that the icons themselves are white so they display clearly in my app.
