title: Display Rails 6 show view as embed shopify page
body: <p>I have an app, which is hosted on heroku, already installed in my test shop and ready to use. The app is embed in the admin. The App creates a rails view, which shall appear embed in the shop frontend as a page, like it would be created in the pages section by a shop admin.</p>
  <p>Ive read about app bridges and app proxies which in my opinion dont give me the functionality I want.  One thing I came along is building iframes on the fly on an API-created page, but i dont know if its the best way to accomplish it.</p>
  <p>App functionality:</p>
  <ol>
  <li>App does something in the shopify admin and creates a link - done</li>
  <li>The link will be copied by the admin/user to his navigation - will be done manually</li>
  <li>If a customer clicks on the link in the shop-frontend-navbar, the link shall open as a shopify-page, so that the user thinks he is still in the shop-frontend.</li>
  </ol>
  <p>How do I do that?</p>
