Add page to page builders

What is the procedure for adding a page to the page builders?  I have a module that does not have a view in page builders and I need to add it.

add an entry to "sys_page_compose_pages"

and extend your view file class to Page View class

bx_import('BxDolPageView');
class MyViewPage extends BxDolPageView
{
      function MyViewPage()
      {
            parent::BxDolPageView('my_page_in_table');
      }
}

you can extend to twig view class too, examples can be found in groups, events type module.

Good Luck
