How to set/pass session configuration from Apache Superset

[mmuru]

Kyuubi 1.9.1, Spark SQL engine on K8S

In DBeaver connection URL, one can include default;#spark.driver.memory=4g;spark.executor.instances=10;spark.executor.cpu=2;spark.executor.memory=4g for each connection session.

Similar to I would like to set/pass session configuration from Apache Superset. I tried the following while adding database connection but it throws Kyuubi sql Exeception
sparksql://localhost:10009/default
Advanced -> others -> engine_config

"connect_args":{
"configuration": {
    "spark.driver.memor": "4g",
    "spark.executor.instances": "5", 
    "spark.executor.cpu":"2", 
    "spark.executor.memory":"4g"
  }
}

Please, let me know how can I achieve the same in the Superset? By default, it always starts 2 instances or whatever configured in the spark-default.conf file.

Thanks in advance.
