Add tags through Acrobat SDK

I need to add tags programmatically to my PDFs which are not tagged PDFs and I want to create tags by Acrobat SDK. I can make menu available by

mApp.MenuItemExecute("ShowHideNavigationPane");

mApp.MenuItemExecute("ShowHideTagsPanel");

but I do not know how to run "Add Tags to Document" menu. Following is not working:

mApp.MenuItemExecute("AddTagsToDocument");

Thanks for help
