What is the current behavior?

When using the inviteUserByEmail() function, the user_metadata field remains empty, even when data is provided.

The inviteUserByEmail() function now successfully sends user metadata when provided. The user_metadata field will correctly include the submitted data.

    'last_name': "one",
  },
);
