Custom header height on NavigationPane

[WinXaito]

I know this is not really conform to microsoft fluent, but I would like to add custom information in top of the NavigationPane.

So do you think there is a possibility to add custom height header ?

There is already:

NavigationView(
  pane: NavigationPaneSize(
    topHeight: <your height here>,
  ),
),

My bad. Thanks

I test and that's not work (topHeight is only used when we have a top navigation)

But I use a left navigation pane:
