Adding Google Password Manager as option in Mac Keychain list?

Hey all - I was having a tough time finding any info on this in my research, but I'm looking for a way to add Google Password Manager into my macOS Keychain as an option for apps to pull autofill information from in addition to iCloud Keychain. But I don't want to merge the two yet. This option exists in iPhone (I'm on iOS 17.4) where I can toggle on both iCloud Keychain and Google Password manager.

I'd like to be able to do the same in macOS (I'm on Sonoma 14.3). Any insights from the community on how to make this happen? And to be clear, I'm not looking to import my Google passwords into iCloud. I'd like to keep them separate still.

Thank you!
