How to change priority in 3 nodes cluster

[balait4]

I have 3 member cluster (6.0.6) and I want to set or give more priority for 2 members and less for one member.
I tried setting automationConfig which is not working. Also I had set under memberConfig which is not working.

automationConfig:
    replicaSet:
      settings:
        members:
          - _id: 0
            host: mongodb-i-srv-0.mongodb-i-srv.mongodb-i.svc.cluster.local:27017
            priority: 2
          - _id: 1
            host: mongodb-i-srv-1.mongodb-i-srv.mongodb-i.svc.cluster.local:27017
            priority: 2
          - _id: 2
            host: mongodb-i-srv-2.mongodb-i-srv.mongodb-i.svc.cluster.local:27017
            priority: 1
        electionTimeoutMillis: 10000
    processes:
          - name: mongodb-i-srv-0
            hostname: mongodb-i-srv-0.mongodb-i-srv.mongodb-i.svc.cluster.local
            processType: mongod
            version: "6.0.6"
            disabled: false
            args:
              net:
                port: 27017
              replication:
                replSetName: mongodb-i-srv
          - name: mongodb-i-srv-1
            hostname: mongodb-i-srv-1.mongodb-i-srv.mongodb-i.svc.cluster.local
            processType: mongod
            version: "6.0.6"
            disabled: false
            args:
              net:
                port: 27017
              replication:
                replSetName: mongodb-i-srv
          - name: mongodb-i-srv-2
            hostname: mongodb-i-srv-2.mongodb-i-srv.mongodb-i.svc.cluster.local
            processType: mongod
            version: "6.0.6"
            disabled: false
            args:
              net:
                port: 27017
              replication:
                replSetName: mongodb-i-srv
type: ReplicaSet
memberConfig:
  - priority: '2'
    votes: 1
  - priority: '2'
    votes: 1
  - priority: '1'
    votes: 1

When I tried setting this manually as well its getting revert immediately.

cfg = rs.conf()
cfg.members[0].priority = 5
cfg.members[1].priority = 5
cfg.members[2].priority = 2
rs.reconfig(cfg)
