Default notification translation

[T1mey]

Hello,

how do I translate the title and the description of the default notification.
So that SAP Workzone (Notifications) can decide in which language it should be shown (IMHO --> the language in which the user who received the notification is logged in --- and as fallback a fallback language (en?) ).

Do I need to pass the whole object to the alert function in this way?

 alert.notify({
                recipients: rec,
                Properties: [
                    {
                      Key: 'title',
                      IsSensitive: false,
                      Language: 'en',
                      Value: "Title EN",
                      Type: 'String'
                    },
                    {
                      Key: 'title',
                      IsSensitive: false,
                      Language: 'de',
                      Value: notBundle.at("title", "de"),
                      Type: 'String'
                    }
                    ...
                ],
            });

How do I set a fallback then?
