How to change Android navigation/status bar color?

How can I control the navigation/status bar during runtime? I mean changing the color, visibility and transparency. I cannot believe it's so hard to find something...

The only thing I found is this script: https://github.com/zeh/unity-tidbits/blob/master/application/ApplicationChrome.cs
and this asset: https://assetstore.unity.com/packages/tools/gui/mobile-status-navigation-bar-187818#reviews
but unfortunately, both of them are not supported and are outdated.

Navigation and status bars are an integral part of the user experience on Android. Unbelievable that almost nobody talks about it and there is nothing good on the Asset store...
