/**
 * Use the composable `useSignInAnonymous` to sign in a user anonymously.
 *
 * As a result, the user will have the `anonymous` role and subsequent set of permissions.
 * The user can then be converted to a regular user at a later stage using email+password sign-up, passwordless email (magic link), or passwordless SMS.
 *
 * @example
 * ```tsx
 * const { signInAnonymous, isLoading, isSuccess, isError, error } = useSignInAnonymous()
 *
 * watchEffect(() => {
 *   console.log(isLoading.value, isSuccess.value, isError.value, error.value);
 * })
 *
 * const handleFormSubmit = async (e) => {
 *   e.preventDefault();
 *
 *   await signInAnonymous();
 * }
 * ```
