How can I simulate a medium or high-risk fraud alert on Braintree?

We’re using a built-in Shopify Fraud analysis tool.

Payment gateway: Braintree (test-mode)

I’ve tried dozens of different combinations like different shipping/billing addresses (different countries).

Different IPs

etc.

Then, I used Order Risk API but it doesn’t have access to Fraud alerts created by Shopify.

I can create my own alerts, edit/remove them. But I can’t get access to Shopify’s alerts.

When I try to private app API to change fraud alert created by Shopify from the Low to Medium or High I always got a 401 error.

Is it possible to simulate a Medium/High-risk fraud alert?
