Which of the following is NOT a function of a connector in flow processing?

The function of connectors in flow processing is primarily to establish relationships between flow shapes and to facilitate the movement of the flow between different steps or actions in a process.

The correct choice highlights that defining user-triggered actions is not a function of connectors. Connectors are designed to illustrate paths and direct the flow of execution through a process, not to define the specific actions that a user might take.

Connectors serve multiple important roles: they define the order of events by showing how one action leads to another, indicate possible branches in a process by diverging the flow into multiple paths based on certain conditions, and clearly connect different flow shapes illustrating the flow of the process. These actions are key aspects of visualizing process flows in Pega, but they do not encompass the action of defining the triggers initiated by users.
