I'm sorry if this is not the right place to ask this.
After I SwitchToPage and on the page I have a grid with two lists, I cannot get focus to interact with the lists.
I have tried to call app.SetFocus(menu) but it does not work this way.

var (
	app         *tview.Application
)

func ViewProfiles() *tview.Grid {
	menu := tview.NewList().
		AddItem("New", "", 'n', nil).
		AddItem("Exit", "", 'x', nil).
		ShowSecondaryText(false)

	data := tview.NewList().
		AddItem("Thijs", "seomthing about a phenomeneu", 0, nil).
		ShowSecondaryText(true)

	grid := tview.NewGrid().
		SetRows(0).
		SetColumns(21, 0).
		AddItem(menu, 0, 0, 1, 1, 0, 0, false).
		AddItem(data, 0, 1, 1, 1, 0, 0, false)

	app.SetFocus(menu)
	
	return grid
}

func main() {
	log.SetOutput(os.Stdout)
	log.SetLevel(logrus.DebugLevel)
	log.Info("Gorim start")

	conf.NewConfig()

	app = tview.NewApplication()

	gorimversion := tview.NewTextView().SetTextAlign(tview.AlignCenter).SetText("Gorim v0.0.1")
	activeinfo := tview.NewTextView().SetTextAlign(tview.AlignCenter).SetText("Active Profile: Thijs")
	whoknows := tview.NewTextView().SetTextAlign(tview.AlignCenter).SetText("Who knows")
	mainbody := tview.NewPages()
	footer := tview.NewTextView().SetTextAlign(tview.AlignCenter).SetText("footer")
	pageMods := tview.NewTextView().SetTextAlign(tview.AlignCenter).SetText("mods")
	pageConfigurations := tview.NewTextView().SetTextAlign(tview.AlignCenter).SetText("configs")
	pageSettings := tview.NewTextView().SetTextAlign(tview.AlignCenter).SetText("settings")

	grid := tview.NewGrid().
		SetRows(1, 0, 1).
		SetColumns(20, 0, 20).
		SetBorders(true).
		AddItem(gorimversion, 0, 0, 1, 1, 0, 0, false).
		AddItem(activeinfo, 0, 1, 1, 1, 0, 0, false).
		AddItem(whoknows, 0, 2, 1, 1, 0, 0, false).
		AddItem(mainbody, 1, 0, 1, 3, 0, 0, false).
		AddItem(footer, 2, 0, 1, 3, 0, 0, false)

	mainbody.AddPage("profiles", ViewProfiles(), true, true)
	mainbody.AddPage("mods", pageMods, true, true)
	mainbody.AddPage("configurations", pageConfigurations, true, true)
	mainbody.AddPage("settings", pageSettings, true, true)
	grid.SetInputCapture(
		func(event *tcell.EventKey) *tcell.EventKey {
			if event.Rune() == 'p' {
				mainbody.SwitchToPage("profiles")
			}
			if event.Rune() == 'm' {
				mainbody.SwitchToPage("mods")
			}
			return event
		})

	app.SetRoot(grid, true).SetFocus(mainbody)

	mainbody.SwitchToPage("mods")

	if err := app.Run(); err != nil {
		fmt.Printf("Error running application: %s\n", err)
	}
