I'm just starting with Go and tview,
I looked at grid.go, NewGrid should return *Grid but sth goes wrong here. I can not add items to grid.
it looks like NewGrid returns *Box instead of *Grid. whats going on here?

package ui

import (
	"github.com/rivo/tview"
)

func newPrimitive(text string) tview.Primitive {
  return tview.NewTextView().
          SetTextAlign(tview.AlignCenter).
          SetText(text)
}

func CreateMainView() {
  leftSideView:= newPrimitive("test")

  mainGrid := tview.NewGrid().
              SetRows(0).
              SetColumns(30, 0).
              SetBorder(true)

  mainGrid.AddItem(leftSideView, 0, 0, 1, 1, 0, 0, true)
	
  if err := tview.NewApplication().SetRoot(mainGrid, true).SetFocus(mainGrid).Run(); err != nil {
		panic(err)
	}
}

$ go run main.go
# github.com/----/----/ui
ui/layout.go:21:12: mainGrid.AddItem undefined (type *tview.Box has no field or method AddItem)
