wxWidgets. Creating a new page within wxAuiNotebook on command - wxwidgets

Question

How do I add a page to wxAUINoteBook? I wish to be able to click: File->New, and then have a new tab pop in. I understand how to do this using wxAuiMDIChildFrame within a parent frame but the child frame is a class on its own and a new page is not. Here is what I have so far.
#include "main.h"
MyFrame::MyFrame()
: wxFrame(nullptr, wxID_ANY, "AUItest", wxPoint(50, 50), wxSize(800, 450), wxDEFAULT_FRAME_STYLE)
{
wxMenuBar* menubar = new wxMenuBar;
wxMenu* menufile = new wxMenu;
menufile->Append(1001, "New");
menufile->Append(1002, "Open");
menufile->Append(1003, "Save");
menufile->Append(1004, "Exit");
menubar->Append(menufile, "File");
SetMenuBar(menubar);
wxAuiNotebook* notebook = new wxAuiNotebook(this, -1, wxPoint(-1, -1),
wxSize(-1, -1), wxNB_TOP | wxAUI_NB_CLOSE_ON_ACTIVE_TAB);
wxPanel* panel1 = new wxPanel(notebook, wxID_ANY, wxDefaultPosition, wxDefaultSize);
wxPanel* panel2 = new wxPanel(notebook, wxID_ANY, wxDefaultPosition, wxDefaultSize);
wxPanel* panel3 = new wxPanel(notebook, wxID_ANY, wxDefaultPosition, wxDefaultSize);
notebook->AddPage(panel1, wxT("Sheet1"));
notebook->AddPage(panel2, wxT("Sheet2"));
notebook->AddPage(panel3, wxT("Sheet3"));
Center();
}
MyFrame::~MyFrame()
{
}
wxBEGIN_EVENT_TABLE(MyFrame, wxFrame)
EVT_MENU(1001, MyFrame::OnMenuNew)
EVT_MENU(1002, MyFrame::OnMenuOpen)
EVT_MENU(1003, MyFrame::OnMenuSave)
EVT_MENU(1004, MyFrame::OnMenuExit)
wxEND_EVENT_TABLE()
void MyFrame::OnMenuNew(wxCommandEvent& event)
{
//How do I add a page on command?
}
void MyFrame::OnMenuOpen(wxCommandEvent& event)
{
}
void MyFrame::OnMenuSave(wxCommandEvent& event)
{
}
void MyFrame::OnMenuExit(wxCommandEvent& event)
{
Close(true);
event.Skip();
}
Thanks for the help,
I'm still learning.
