I am writting a chrome extension that needs to have two domains in its whitelist for the content security policy. I've looked at the official docs, but I still can't seem to figure out the proper syntax.

The following does not seem to work:

"content_security_policy": "script-src 'self' https://foo.com https://example.com; object-src 'self'"

EDIT:

Both my content script and my popup are able to reach foo.com, however, neither can reach example.com.

Are chrome extensions capable of having multiple sources whitelisted in the CSP?
