How do I configure File schema history storage for Debezium MySql connector?

Question

I'm writing a Debezium (2.3.2) Engine program. After running successfully with Postgres, I switched to MySQL but hit the following problem:

Exception in thread "pool-1-thread-1" org.apache.kafka.common.config.ConfigException: Invalid value io.debezium.storage.kafka.history.KafkaSchemaHistory for configuration schema.history.internal: Class io.debezium.storage.kafka.history.KafkaSchemaHistory could not be found.

I want to avoid Kafka entirely, so I don't want to use KafkaSchemaHistory

I tried adding the following properties:

schema.history.internal=io.debezium.storage.file.history.FileSchemaHistory
schema.history.internal.file.filename=mysql-schema-history.dat

But I still get the same error, can anyone give me a clue what the right properties are?
