My answer is go to the topic or session where you want to use Vyew. Go to the dropdown “Add a resource” select “Link to a file or web-site” fill in the tirle of your page, description details etc and pase the url of your Vyew room into the ‘Location’ box, select the other options that you want - keeping the radio button option
‘Same window
Put resource in a frame to keep site navigation visible’
Confirm and that should be it! It works for me like that.
