Cross-domain carrying problem of cookie

currently I have an interface with the address a.com and the page requests b.com . Using CORS to cross-domain, the data is fine and can be returned normally, but how to pass cookie under a.com to b.com ? The request is using fetch , and credentials: "include" has been set, but it still has no effect. The header Cookie is not added to the browser request at all!

how to solve this cross-domain cookie delivery problem? Are there any great gods who have the experience to guide them?
