How to publish platform event using the inbound interface?

Introduction:-

Salesforce platform event provides an event-bus for streaming and integration using event-driven publish/subscribe architecture. Creating an event can be done using the inbound or outbound interface.
With the inbound interface, we get data from the outside and with this data, we can create an event into the Salesforce bus.
Platform events enable developers to deliver secure, scalable, and customizable event notifications within the Salesforce platform or from external sources. Platform events are based on a publish-subscribe architecture.
We added new functionality to create and consume platform event and we need to see what and which event is on the event bus.
In Skyvva we can enrich the event data with mapping and process the data after we have mapped the event/message.
If the customer doesn't have Skyvva he needs to do all the mapping and transformation using Apex code in the trigger.
Hence these are the added value with Skyvva. So in this tutorial, you will get to know How to publish platform event using the inbound interface?
