Does apple keychain work on Chrome?

No. See the following from https://9to5mac.com/2017/02/11/icloud-keychain-guide-to-password-management/

Password managers also work across various systems. iCloud Keychain only works within the Apple ecosystem. Even though you may use Google Chrome on your Mac, you won’t be able to use your iCloud Keychain in that browser. If you use Google Chrome as your default web browser, saving your user credentials there will most likely default to its password manager (unless you have a third party one configured). Because of this, your credentials aren’t saved into Apple’s iCloud Keychain and thus won’t sync over to your other devices like your iPhone and iPad. It can be potentially confusing when you go to your phone and realize none of your iCloud Keychain passwords are there as expected.
