How to create a new event on outlook with HTTP node

Hello everyone,
I’m building an n8n workflow and I’m having trouble creating a new event in Outlook. The Outlook node doesn’t include fields like location, attendees, etc., so I’m using an HTTP Request node instead.

Could someone explain what I’m supposed to enter in each field-especially the JSON Body? I’d really appreciate an example of how the JSON should look for creating an Outlook event.
