S3 Source Connector Using No Keys

Can the s3 source connector authenticate with AWS by assuming an IAM role? My current connector configuration is below. The connector never starts.

connector.class= “io.confluent.connect.s3.source.S3SourceConnector”
s3.credentials.provider.class= “io.confluent.connect.s3.auth.AwsAssumeRoleCredentialsProvider”
s3.credentials.provider.class.arn =
s3.region = “us-east-1”
format.class= “io.confluent.connect.s3.format.avro.AvroFormat”
partitioner.class= “io.confluent.connect.storage.partitioner.DefaultPartitioner”
topic= “Topic1”
tasks.max= 1
confluent.topic.bootstrap.servers = <lists of brokers using port 9098>
tasks.max= 1
s3.bucket.name= s3-bucket-name

Any help would be greatly appreciated.
