Problem with Pendo API Key for Track Events (Non-web environments)

Hi everyone,

I want to use Pendo track events in a desktop application. I'm using the following code snippet to send track events to Pendo: https://engageapi.pendo.io/#e45be48e-e01f-4f0a-acaa-73ef6851c4ac

However, I'm getting a 401 (Unauthorized) status code. I'm using the shared key for track events in the application settings as the Pendo_trackEventSecret_Key. What am I doing wrong?
