Can I see my Gmail eMails from my on-line iCloud account?

I have several Gmail eMail accounts along with my iCloud eMail account. I use Apple Mail on my Mac Mini (i7 Intel 2018 model) running macOS 14.6.1 Sonoma. When I go to my iCloud account on my Mac via Safari and check my eMail - I only see my 440 iCloud eMails there, not the 1600 or so Gmails. Is there a way to get iCloud to show my Gmails as well?? (Like it does on my Mac in Apple Mail).

Thanks for any comments on how this works. I'm thinking of moving from 200 gb of iCloud to 2 tb of iCloud storage and would be nice to have my Gmail eMails backed up there as well (or as said, directly in the iCloud eMail area).

Best regards,

Steve Schulte
