How to change AccentColor in WPF .NET 9 with Fluent Theme

Hi, i have a .NET9 WPF app and i'm using the Fluent Theme (https://learn.microsoft.com/en-us/dotnet/desktop/wpf/whats-new/net90?view=netdesktop-9.0#apply-the-theme)
Since you can alter the theme (dark/light) easily for the app, I was wondering if there is also an easy way to change the AccentColor for only this one app?
Does anybody know?
