How to use the @requestnetwork/types.ExtensionTypes.PnAddressBased function in @requestnetwork/types

copiedExtensionState[extensionAction.id] = applyCreation(
      isValidAddress,
      extensionAction,
      timestamp,
    );

    return copiedExtensionState;
  }

  // if the action is not "create", the state must have been created before
  if (!requestState.extensions[extensionAction.id]) {
    throw Error(`The extension should be created before receiving any other action`);
  }

  if (extensionAction.action === ExtensionTypes.PnAddressBased.ACTION.ADD_PAYMENT_ADDRESS) {
    copiedExtensionState[extensionAction.id] = applyAddPaymentAddress(
      isValidAddress,
      copiedExtensionState[extensionAction.id],
      extensionAction,
      requestState,
      actionSigner,
      timestamp,
    );

    return copiedExtensionState;
  }

  if (extensionAction.action === ExtensionTypes.PnAddressBased.ACTION.ADD_REFUND_ADDRESS) {
    copiedExtensionState[extensionAction.id] = applyAddRefundAddress(
      isValidAddress,
      copiedExtensionState[extensionAction.id],

throw Error(`Refund address already given`);
  }
  if (!requestState.payer) {
    throw Error(`The request must have a payer`);
  }
  if (!Utils.identity.areEqual(actionSigner, requestState.payer)) {
    throw Error(`The signer must be the payer`);
  }

  const copiedExtensionState: ExtensionTypes.IState = Utils.deepCopy(extensionState);

  // update refund address
  copiedExtensionState.values.refundAddress = extensionAction.parameters.refundAddress;
  // update events
  copiedExtensionState.events.push({
    name: ExtensionTypes.PnAddressBased.ACTION.ADD_REFUND_ADDRESS,
    parameters: { refundAddress: extensionAction.parameters.refundAddress },
    timestamp,
  });

  return copiedExtensionState;
}
