How to get token for submittion?

[ugd-mg]

Hello everyone,

In EU DCC Validation Export and Submit process, step 2 mentions:
_"By pressing the submit button, you will be asked to enter a token which you will receive by email. In the next pop-up window, please select the upload button, navigate to your standard upload folder, select the file appropriate and press the Send button

Visit the validation portal and submit the uploaded results.json. To access the portal, use the token linked to your country."_

Where do I enter my email address for token request? Thank you
