Documentation - Stores> Configuration> Experius> CSP> Whitelist

[measureddesigns]

I'm a bit confused as to if I still need to set up a custom module with a csp_whitelist.xml file.

I see there's a section in Magento admin under Stores> Configuration> Experius> CSP> Whitelist

I can add an entry here e.g. img-src / cdn.klarna.com
But it doesn't seem to whitelist future blocked URLs in the main blocked grid.

I'm currently whitelisting entries in the blocked grid, adding the URL to the whitelisting section, then deleting the entry. However new entries are still blocked and the notification never goes away.
"Content Security Policy Issue Found
View CSP Reports - make sure you update the Content Security Policy or your site won`t work properly in 2.4."

I can also select all entries but can't whitelist or delete all.
