Intermediate events are specifically used for event calls at certain specific stages or milestones of a process. When the process flows to this node, it first calls the external event bound to this node, and then automatically flows to the next node of the process. The following is an example of a process design diagram. The graphic node "Notify Business" is a node type of an intermediate event, which is a status mark for the process entering the business stage.

On the node attributes of the intermediate event, you can define the conditional expression for its triggering.
