I recently delivered a webcast for https://www.intlock.com, makers of the excellent CardioLog Analytic suite for SharePoint, Teams and Yammer adoption. The webcast was based around using Bots in Microsoft Teams to improve Collaboration and Adoption, and it discussed these concepts as well as including high level demos of various ways to create Bots and Bot-like experiences (including Power Automate, Power Virtual Agents, Bot Framework Composer, and Bot Framework), as well as a brief comparison of these options.
