How to get dark mode

[Rocky-25]

I'm using another library for some charts/graphs and it has allows a parameter to be passed for dark mode. I'm really struggling to get this out from FluentUI.

I've added this to the page I need to know
<FluentDesignTheme StorageName="theme" @bind-Mode=Mode/>

And in the code have this

public DesignThemeModes Mode { get; set; }

protected override async Task OnInitializedAsync()
{
Console.WriteLine($"Mode: {Mode}");
}

But it always prints "Mode: System", regards of being in dark or light mode. What am I doing wrong? How do I get this value correctly?

Thanks!
