To add a startup script when deploying a windows instance in GCP

Question

I'm deploying a Windows Instance in GCP with couple of startup scripts using the metadata option in the gcp_compute_instance module, as the instance is getting created as expected but the startup scripts are not getting executing, kindly refer the below task and do suggest what changes I need to do to execute the startup script (first creating a local admin user with password and then setting winrm basic authentication to true)

   - name: create a instance
     gcp_compute_instance:
         state: present
         name: "{{ vm_name }}"
         machine_type: "{{ machine_type }}"
         metadata:
           startup-script: |
                   New-LocalUser -AccountNeverExpires:$true -Password ( ConvertTo-SecureString -AsPlainText -Force 'Password123!') -Name 'adminuser1' |Add-LocalGroupMember -Group administrators
                   winrm set winrm/config/service '@{AllowUnencrypted="true"}'
                   winrm set winrm/config/service/auth '@{Basic="true"}'
         disks:
           - auto_delete: true
             boot: true
             source: "{{ disk }}"
           - auto_delete: true
             boot: false
             interface: NVME
             type: SCRATCH
             initialize_params:
                     disk_type: local-ssd
           - auto_delete: true
             boot: false
             interface: NVME
             type: SCRATCH
             initialize_params:
                     disk_type: local-ssd
         network_interfaces:
           - network: "{{ network }}"
         zone: "{{ zone }}"
         project: "{{ gcp_project }}"
         auth_kind: "{{ gcp_cred_kind }}"
         service_account_file: "{{ gcp_cred_file }}"
         scopes:
           - https://www.googleapis.com/auth/compute
     register: instance

The fine manual says the key should be, in your case, windows-startup-script-ps1: since that script is powershell
