In a UiPath project that uses State Machines, under what circumstances should the Final State...

The Final State activity is used to indicate the end of a state machine’s execution, either successfully or with an error1. The Final State activity has only one section, Entry, where you can add activities to perform before exiting the state machine2. You can have more than one Final State in a state machine, but you can only create one Initial State3. The Final State activity should be used when you want to mark the completion or termination of a state machine’s execution, not when initiating the first state, handling complex logic, or having multiple transitions.
