Which actions are not available for Canvas apps in Power Apps when using model-driven apps?

In Power Apps, model-driven apps and canvas apps have differing capabilities and functionalities. Model-driven apps are primarily built on Microsoft Dataverse and focus on the underlying data model, business logic, and application lifecycle, while canvas apps provide more design flexibility with a drag-and-drop interface, allowing users to create customizable layouts and workflows.

When considering the specific actions like showing/hiding fields, enabling/disabling fields, and generating business recommendations based on business intelligence (BI), these functionalities are specifically limited in model-driven apps in comparison to canvas apps. Model-driven apps utilize a more structured approach where field visibility and interactivity are often dictated by the underlying data model and business logic rather than the free-form design approach of canvas apps.

Choosing to indicate that "all of the above" actions are not available emphasizes the limitations inherent within model-driven apps when attempting to utilize functionalities available in canvas apps. The focus in model-driven apps is more on the data and less on customized user interactions, which is why these specific actions are not applicable in that context. Therefore, identifying "all of the above" as the correct response captures the essence of the restrictions faced when working within the framework of model-driven applications regarding user interactivity with fields.
