* modify the Content-Security-Policy sent by Nextcloud. Per default only JavaScript,
* stylesheets, images, fonts, media and connections from the same domain
* ('self') are allowed.
*
* Even if a value gets modified above defaults will still get appended. Please
* notice that Nextcloud ships already with sensible defaults and those policies
* should require no modification at all for most use-cases.
*
* This class allows unsafe-eval of javascript and unsafe-inline of CSS.
