Build not appearing inside the test flight section.

Hello, I have created a production build with eas, in the aim of testing my app with Testflight before submitting it. The build was successful. I used to transporter to download the ipa file. Now the build (with the new version number) appears inside the App Store section (as needing to be finalized before submission). However, no traces of it inside the TestFlight section. What am I missing here ?
