Which of the following is NOT a way to execute a process in UiPath Orchestrator?

In UiPath Orchestrator, executing a process typically involves interactions with the robot tray, scheduling jobs, or starting jobs directly from the Orchestrator interface. The robot tray serves as a user interface for individual robots and allows users to view available processes and execute them directly from their workstations. Scheduling is a powerful feature that automates when processes will run, enabling them to be triggered at designated times without manual intervention.

Starting a job relates to initiating a specific process in Orchestrator, where jobs can be launched based on triggers, schedules, or user-initiated commands.

However, executing a process directly from a library is not a standard method of execution within Orchestrator. In RPA, libraries are often designed to contain reusable workflows and components that can be invoked from other processes but do not serve as a direct execution point. Processes must be published to Orchestrator or executed through the robotic components, not just retrieved from libraries. Thus, this option is inherently not a valid way to directly execute a process within the context of UiPath Orchestrator.
