One of the preview features in Copilot Studio is the Dataverse data source, but we have already tested it and it works quite well.
Additionally, we have tested the power of actions using the Dataverse connector and it is fantastic what we can do.
A plus, in the video I show you that the results obtained by Copilot in Power Apps are the same as the results obtained when you use Dataverse as knowledge, is it using the same model?
