Content Security Policy Customization

[IvanFrias]

Hi Looker team,

We are currently customizing Looker by injecting a custom javascript file that modifies the UI ( iframe ), embedded on our application through SSO Embedding.

We recently upgraded to 22.16.35 and we are experiencing issues due to the fact that Looker is returning the Content-Security-Policy with the strict-dinamic option turned on.

Questions: Is there a way to customize the Content Security Policy returned by Looker ? Please do note that this is a customer-hosted instance.
