[Java dapr SDK]io.dapr.client.domain.CloudEvent mismatch the defination

According to
https://docs.dapr.io/developing-applications/building-blocks/pubsub/pubsub-cloudevents/
v1.0 CloudEvent should contains parameter
[
traceparent
traceid
tracestate
topic
pubsubname
time].
But when we are using dapr-sdk 1.8.0, there is no
[
traceparent
traceid
tracestate
topic
pubsubname
time]
My question is why don't java SDK CloudEvent class don't have these items?

I'm asking because we need the topic dynamically to get some information from the topic....

Inizia confrontando la documentazione di Dapr CloudEvents v1.0 con la classe CloudEvent del Java SDK 1.8.0. Verifica se traceparent, traceid, tracestate, topic, pubsubname e time sono rappresentati altrove o omessi, quindi determina se l’issue richiede un chiarimento o una modifica all’SDK.
