AngualrJS OIDC Client Silent Renew page

问题:

I am struggling to understand how this silent renew process works. as per what I Read I understood that the html page will be kept in an iframe and it keeps pinging server for renewing token.

I have an angular application, typically we package everything into one simple index.html file and rest will be inserted based on route (ui-router, template caching).

So In my context, should we keep this html packaged? or should it be separate html page lives alongside index.html?
