Slesforce platform event

Hi Everyone,

We are facing an issue where Salesforce platform event are not audible in Mulesoft.

We have created a Platform event object , a flow to create platform event on lead create/update. Mulesoft subscribed to that platform event has no clue when platform event triggered.

We are not able to see platform event records directly but we have created a flow on platform event object and that flow trigger one email when we create/update a lead.

We are still in confusion why mulesoft cannot see that platform event and below query results even not show any platform event delivered. Even though platform event flow shooting emails.

Please help if you faced this issue too. 

SELECT Name, StartDate, EndDate, Value FROM PlatformEventUsageMetric

WHERE Name='PLATFORM_EVENTS_DELIVERED'

Thanks,

Prerna
