Couldn't connect to dpms while creating dataproc using airflow operator

I have a service created for dataproc metastore(in same project as composer's) and trying to use it instead of my hive warehouse. I could successfully run this using gcloud commands but when I am trying to use any airflow operators like DataprocClusterCreateOperator or DataprocCreateClusterOperator, I couldn't pass this external dpms to my dataproc cluster. I see that it is accepting some arguments like 'dataproc_metastore_service' without any syntax error but it is not actually using this argument- when cluster is created, dpms field is 'none' in cluster configuration.

Code I am trying to execute:

create_cluster=DataprocClusterCreateOperator(
task_id='create_cluster',
cluster_name=CLUSTER_NAME,
project_id=PROJECT_ID,
region='us-east4',
zone='us-east4-b',
subnetwork_uri="projects/**************/shared-np-east-green-subnet-2",
internal_ip_only=True,
enable_component_gateway=True,
num_masters=1,
master_machine_type='n1-standard-4',
master_disk_size=30,
num_workers=2,
worker_machine_type='n1-standard-4',
worker_disk_size=30,
init_action_timeout='10m',
image_version='2.0-rocky8',

'dataproc:metastore-config:dataproc-metastore-service':projects/common_project/locations/us-east4/services/custom_service_name'},
metadata=[("http-proxy","http://proxy.ebiz.example.com:9290"),

("mysql-root-password-secret-name","mysql-root-password,exmp-password-secret-name=exmp-password")],
idle_delete_ttl=300,
dag=dag
)

In the above code, I also tried 'dataproc_metastore_service = 'projects/common_project/locations/us-east4/services/custom_service_name' to pass the dpms argument but didn't work. As an alternate approach, I am defining inside properties arguments but no use

Please help me with any thoughts.

I got the answer. Pasting it here if it helps others
