 1. `dotnet add package Octokit.Webhooks.AzureFunctions`
 2. Create a class that derives from `WebhookEventProcessor` and override any of the virtual methods to handle webhooks from GitHub. For example, to handle Pull Request webhooks:
 
     ```C#
     public sealed class MyWebhookEventProcessor : WebhookEventProcessor
     {
-        protected override Task ProcessPullRequestWebhookAsync(WebhookHeaders headers, PullRequestEvent pullRequestEvent, PullRequestAction action, CancellationToken cancellationToken = default)
