Kafka connect not loading s3source plugin

Kafka Connect Managed Connectors
1

I have kafka-source connector jar , which is downloaded from confluent , in my plugin.path and when pod starts , I can see the logs, that plugin.path (/usr/share/java/kafka/s3-connect) is read.
but somehow this “s3source” connector is not registering.

INFO Scanning for plugin classess. This might take a moment ...
INFO Loading plugin from: /usr/share/java/kafka/s3-connect/kafka-connect-s3-source-2.6.0.jar (org.apache.kafka.connect.runtime.isolation.PluginScanner:75)
INFO Registered loader: PluginClassLoader{pluginLocation=file:/usr/share/java/kafka/s3-connect/kafka-connect-s3-source-2.6.0.jar} (org.apache.kafka.connect.runtime.isolation.PluginScanner:80)

Then further down I can see some plugins added like this , but no source connector

INFO Added plugin 'org.apache.kafka.connect.transforms.ExtarctField$Value'
INFO Added plugin 'org.apache.kafka.connect.converters.FloatConverter'

INFO Added alias 'Json' to plugin 'org.apache.kafka.connect.json.JsonConverter'
INFO Added alias 'StringConverter' to plugin 'org.apache.kafka.connect.storage.StringConverter'
INFO Added alias 'MirrorSource' to plugin 'org.apache.kafka.connect.mirror.MirrorSourceConnector'
INFO Added alias 'Directory' to plugin 'org.apache.kafka.common.provider.DirectoryConfigProvider'

I’m running distributed mode worker…
Can someone help me , why s3source connector not loading and configuring

the output from curl -s http://localhost:8083/conenctor-plugins | jq
