Debezium server sink oracle database to pulsar without default namespace "public/default"

I set the property "debezium.sink.pulsar.producer.topicName=persistent://IT-DW/test1/imes111_uat" in conf/application.properties.but debizium auto create topic in pulsar default namespace "pulbic/default'.Then, I read the document "https://debezium.io/documentation/reference/1.5/operations/debezium-server.html#_apache_pulsar", it said "The Pulsar module supports pass-through configuration. The message producer configuration properties are passed to the producer with the prefix removed. The topic is set by Debezium." What means is "The topic is set by Debezium?How can i sink to the topic that i set? ie. persistent://IT-DW/test1/imes111_uat
