How to use the n8n-workflow.NodeHelpers.getNodeWebhooks function in n8n-workflow

const returnData: IWebhookData[] = [];

	let parentNodes: string[] | undefined;
	if (destinationNode !== undefined) {
		parentNodes = workflow.getParentNodes(destinationNode);
		// Also add the destination node in case it itself is a webhook node
		parentNodes.push(destinationNode);
	}

	for (const node of Object.values(workflow.nodes)) {
		if (parentNodes !== undefined && !parentNodes.includes(node.name)) {
			// If parentNodes are given check only them if they have webhooks
			// and no other ones
			continue;
		}
		returnData.push.apply(returnData, NodeHelpers.getNodeWebhooks(workflow, node, additionalData));
	}

	return returnData;
}
