How to add namespace annotations?

All,

I have thousands of namespaces and most of them were created without having owner information before automation. Now I wish to add that missing information to all namespaces and looking for a best command to add owner id & email as you see below.

    vusers@1.11.11.21~]$ kubectl describe ns cpnp-dev-powerui
    Name:         cpnp-dev-powerui
    Labels:       kube.company.com/role-bound=invalid
                  project.lob=rts
                  project.hjad=bpjp
    Annotations:  appreleasename: dev
                  environment: nonprod
                  internetfacing: No
                  launchedby: k8s:ciccd:automation
                  lob: rts
                  namespacetype: user_namespace
                  owner-eid: 123456
                  **owner-emailid: firstname.lastname@company.com
                  project-distro-emailid: firstname.lastname@company.com**
                  projectname: powerui
                  vsad: bpjp
    Status:       Active
    
    No resource quota.
    
    No resource limits.

I wish to edit existing namespaces and add below annotations

          owner-eid: 123456
          owner-emailid: firstname.lastname@company.com
          project-distro-emailid: firstname.lastname@company.com

Thanks
Bala
