A single iFrame can be configured with these options:
Enabled — when toggled on, the Custom tab will appear in the Analytics dashboard.
URL — the web address of the webpage being embedded, requiring an http:// or https:// prefix.
Webpages applied to the iFrame are third-party resources, and thus do not fall under Proto's scope of support services. If you're troubleshooting getting a valid URL to display, ensure the website supports being iFramed. If the URL's content is behind a login, you may need to be separately signed-in to that platform for the iFrame to display authorized content.
