[fetch-metadata] cors in Sec-Fetch-Mode

Dear Sir/Madam,
The Sec-Fetch-Mode HTTP Request Header could be set to "cors", "navigate",
"nested-navigate", "no-cors", "same-origin", and "websocket". When it is
set to be "cors", is it the same with feature with an OPTIONS preflight
request and would not include cookies by default? I cannot find this direct
answer from section 2.2 in https://www.w3.org/TR/fetch-metadata/. Thanks!
Regards,
June
