Worksheet Change Event to Show Command Button

I can't get this to work, any guidance? If the target is not blank (it starts out blank, then show the button. (I've reworked this in multiple ways and can't come up with the correct language)

Private Sub Worksheet_SelectionChange(ByVal Target As Range)

If Not Intersect(Range("Approved"), Target) Is Nothing Then
        If Not Range("Approved") = "" Then
                cbtEmailMgr.Visible = True
    End If
    
End If

End Sub

Thanks!
