Instead of directly using queues in a Temporal Workflow, the Workflow (which is written with plain code), schedules an Activity that the system is responsible for, behind the scenes, the Activity is just an item put on a queue. Activities have retry policies which are also handled by the system. If an Activity attempt fails and should not retry according to the policy, an exception is thrown in the Workflow to be handled using code.

Using the TypeScript SDK, you can catch that exception here: https://github.com/temporalio/samples-typescript/blob/9d9108...
