There is no MySQL/oracle source type in the oss-only profile

I have built the dremio.oss-only profile of Dremio 4.1, but there is no MySQL/oracle source type while adding new source. The existed source type contains:Amazon Elasticsearch Service,Amazon S3,Azure Data Lake Storage Gen1,Azure Storage,Elasticsearch,HDFS,Hive 2/3.x,MapR-FS,NAS.

Please point me to how can I get MySQL or oracle source type in dremio.oss-only profile, thanks.
