Hi @pierremichaux,
The plugin is free, so I encourage you to test it in your store and for your FedEx account.
For our FedEx account, after providing a Cambodian origin address, I was able to receive rates via FedEx API.
In the documentation, you will find the plugin requirements and a detailed description of how to access the FedEx API.

If you have any additional questions, let me know, I’ll be happy to help.
Best regards,
Tomek
