Integration Issue with Mailgun in Wasp: 'Forbidden' Error Related to EU Domain

Hello,
I'm using Wasp, and I want to send emails using the Mailgun provider, but I'm encountering an issue with a "forbidden" error. After some research, I found that the problem is related to the base URL. For domains created in the EU region, you need to add

.eu

.eu

to the URL, like this:

https://api.eu.mailgun.net/

https://api.eu.mailgun.net/

. Here's the documentation: https://documentation.mailgun.com/docs/mailgun/user-manual/get-started.

Is it possible to fix this issue? I can't find where in the Wasp project the URL is configured to apply this fix while waiting for an official solution.

Thank you.
