Wikijs Graphql: How to create multiple users at a time?

I am trying to create multiple users at a time from a CSV file. Right now I am only able to create one user at a time using the following mutation:

mutation {
  users {
    create (
       email: ""
       name: ""
       passwordRaw:: ""
       providerKey: ""
       groups: [1]
       mustChangePassword: true
       sendWelcomeEmail: false
    ) {
       responseResult {
              succeeded
              slug
              message
       }
        user {
              id
        }
       }
      }
     }

This is working fine for creating a single user. I want to make it easy for me to create multiple users at a time.
