Please describe your bug.

When a new user is created in Cognito, an email with a link that has the initial password and the user's email is sent.
An example of the link would be https://my.webapp/[email protected]&password=12345678

I could not find any documentation or sample that shows how to show the amplify UI for confirm sing-in with new password.

What's the expected behaviour?

I would like to directly show the user the change password interface and somehow pass the username and password that came from the URL query,m so that the user does not have to enter them manually.

I could create my own UI to collect new user password, but I would like to reuse the existing amplify-ui for that.

The best I could do for now is to pre-fill username and password:

formFields={{
      signIn: {
        username: {
          defaultValue: username,
          isReadOnly: true,
        },
        password: {
          defaultValue: password,
          isReadOnly: true,
        },
      },
    }}

However, the user still needs to submit the form, which is not ideal.
After the sign-in form is submitted amiplify-ui correctly shows the change-password form.

In the end, I ended up using useAuthenticator and its' submitForm function:

const auth = useAuthenticator((ctx) => [ctx.authStatus])
...
auth.submitForm({
        type: 'SIGN_IN',
        username: searchParams.get('email'),
        password: searchParams.get('code'),
      })

However, I saw a comment that submitForm is intended for internal use and that it is not mentioned in the documentation for that reason. It would be nice to have an "official" way to achieve this, but for now, this will do the trick.
