How to list multiple links in Google's content_security_policy?

Question

Google Chrome

Hello, the whole question is in the title, you need to list not one link, but two in the "content_security_policy" of the extensions. Tried and through ; and separated by commas. He either does not see, or sees the first one, or even says that the manifest is incorrect, thanks for the help!
What does it look like now

"content_security_policy": "script-src 'self' https://*.exp 'unsafe-eval'; object-src 'self'" ,
