Indico + CERNBox: A VCHEP 2021 use-case

<!--HTML-->Indico is an open-source tool for event management used by the whole CERN community, as well as a large amount (more than 200) of organizations, institutes and research centers. One very prominent workflow in Indico is to attach files to an event (slides, documents, etc.). This presented a perfect opportunity to integrate CERNBox into the service, by allowing users to attach files stored in their CERNBox space. This talk presents the upcoming new feature and the findings in this cooperation, as well as a secondary use case for the paper review flow in cooperation with VCHEP21 organizers.
