On the start page of contracts-config you will see which e-mail address has been defined as a Technical contact. If you have not yet defined a technical contact, a message appears at this point with a link to the configuration.

You also have the option of accessing the configuration interface in the Technical contact area and entering a technical contact for the first time or changing an existing contact.

This is how it works

Example configuration of the technical contact

{
    "technicalContacts": {
        "mailAddresses": [
            "max.mustermann@musterfirma.de",
                        "mia.musterfrau@musterfirma.de
        ]
    }
}
