You supply the unique buffer ID value as returned by the action Create Buffer. Note that you can select multiple buffers for removal by clicking the plus icon beside the action, and adding another buffer ID.NOTE: It's important to always remove any dynamically created resources from memory when you no longer need them to prevent memory leaks.
