im trying to use Cloud CDN with backend bucket but it keeps telling me that i should "grant Cloud CDN access to your buckets by adding the Cloud CDN service account to your access control list". I tried modifying the bucket permissions so that "AllUsers" IAM had every permission, but the CloudCDN still kept telling me to "grant Cloud CDN access to your buckets"
So how do you add the Cloud CDN service account to your access control list?
Thanks in advance
