Hi @thomask,
To my understanding; The ‘Professional’ subscription includes access to original QuickSight features (including analysis and dashboard building) as well as some of the new AI features including Chat Agents, Spaces, Research and Flows.
In terms of the Enterprise subscription; you get access to additional features and advanced functionality, including the ability to author automations.
You should not have to make any adjustments to your current role’s to have access to dashboard creation!
