Creating URL for Monday Webhook Integration

Hello, I was following the Introduction to GraphQL API Webinar (Introduction to GraphQL API | webinars - YouTube).

I would like to test the cross-board-automations tool in my account. I created a URL using ngrok to use with Webhook. However, I will lose my ngrok URL when I close out terminal on my computer. Is there a way to create a URL that can use without my terminal staying open?
