Some guidance on how to do this

Tried changing the ALLOW-FROM on nginx http config but this did not work so far (see #4743)

[VickieKarasic]

The ALLOW-FROM protocol is outdated, so adding add_header Content-Security-Policy "frame-ancestors 'self' https://princeton.libwizard.com;" this worked instead.

There wasn't further interest in exploring the Articles+ integration, so will close this issue.
