function AccountMappingStatus() {
  const { isMapped, isLoading, evmAddress, refresh } = useCheckMappedAccount();

  if (isLoading) return <div>Checking mapping status...</div>;

  if (isMapped === false) {
    return (
      <div>
        <p>Account not mapped. Please map your account first.</p>
        <button onClick={refresh}>Check Again</button>
      </div>

Check specific address:

const { isMapped, evmAddress } = useCheckMappedAccount(
