Cannot get API Credentials for testing on addons.allizom.org

Hi !

I wish I can get an API key to use the Staging addons API on https://addons.allizom.org/api/v5/ (External API — addons-server documentation)

I went on Mozilla accounts and asked for the key but no email were sent (I tried with several accounts).

Any clue on how I can move forward ?

Cheers,

Etienne
