iCloud Keychain won't save the first (portal) page

I enter the URL for the first page which is the portal page; then I sign in on the link and keychain fills in the username & password correctly. However, the only website that is saved in keychain is the last page. I can't figure out how to save the first (portal) page. I can't just open the second page because it won't accept information. I can only get to the second page through the portal page. Unfortunately I can't figure out a way to edit the website information, i.e. add the portal page so I can get to the second page. Any suggestions?

PS - I'm running Monterey 12.4 on an iMac
