OpenDevEd has been streamling our Google Docs / Sheets / Slides workflows for many years, going back almost until the initial launch of apps script. For more details about all our Add-ons, see Our Tools.
Similar to BZotero for Docs, BZotero for Slides is a plugin for Google Docs. It allows Zotero links to be embedded into Google Slides that point to a site built with Kerko app.
For details, visit our GitHub repository here google-apps-script/repositories and select BZotero for Slides.
