how to import passwords from Microsoft Authenticator to iCloud keychain

Question

I just purchased an Iphone 14 Pro, and I am having trouble using my passwords. They were originally in icloud, but when I purchased a new computer in February , I had to buy Microsoft office. I installed it on my computer, and also on my iphone. Authenticator then was downloaded onto my iphone. The new Iphone, does not work well with my passwords, and I need to move them from authenticator back to icloud. How do I do that?
