How to save and suggest passwords used in browsers?

I'm trying to create a Password Manager app for iOS in SwiftUI.

I would like that when users are logging into an account on a browser, it gets suggested to save that password into my app, as well as when they want to access a website of which the password is already stored, it get suggested for an autofill.
Is there a way to implement this into my app?

If not automatically, is there another way to make it? I noticed that other Password Managers available on the AppStore use an extension that you can add to your browser, but I image this would be more complicated.

Thanks to everyone!
