It seems that the documentation is missing words in this segment:
https://firebase.google.com/docs/auth/unity/anonymous-auth#convert-an-anonymous-account-to-a-permanent-account

> When the user signs up, complete the sign-in flow for the user's authentication provider up to, but not including, **calling one of the methods**. For example, get the user's Google ID token, Facebook access token, or email address and password.

What methods are referred to here?

> **Get an for** the new authentication provider:

"Get an" what?

> Pass the object to the sign-in user's method:

No method specified after the double-points.

> If the **call to succeeds**, the user's new account can access the anonymous account's Firebase data.

"Call to" what?

Details on the context would be greatly appreciated!
