An agent is currently working in their Home session with no additional sessions open. How would they search through their organization's available account list?

The Application bar is the correct method for an agent to search through their organization's available account list while working in their Home session. This bar typically contains access to various functionalities and modules within Dynamics 365, allowing users to navigate quickly and efficiently.

In this case, the Application bar would provide a dedicated search function that can be utilized to look up accounts among other entities, making it the most direct and effective means to access the account list. Agents often rely on this area to find information quickly without needing to navigate away from their current session or affecting their workflow.

While other options might suggest possible navigation methods, they do not specifically cater to the search functionality required to locate accounts. For instance, the Session Panel is primarily used for managing active sessions rather than searching for records. The Quick Create Button is designed for creating new records rather than for searching existing ones. Similarly, the Customer Summary is more about providing an overview of a specific account rather than a comprehensive search tool.
