Same-Origin Protections for Looker Login Pages
Though public embeds are fully supported, this macro assumes that the URL will be a private embed.
If the user has not already logged in, the Looker URL screen will be displayed within the page in the macro.
Using same-origin protections for your Looker login pages might prevent you from seeing the login screen for private embeds.
If this is causing any problems, set Same-Origin Protections for Looker Login Pages to Enabled.
