how to use PrePostDeploymentScript.Ver2.ps1 within CICD ADF

How am i meant to use this ps1 script in the deployment. the usual build process somehow drops PrePostDeploymentScript.ps1 into the application artifacts folder. however this file isnt copied into the folder the same way?

am i meant to manually take a copy of this version and create a copy task to copy the file to the artifacts folder?

```

- task: AzurePowerShell@5
displayName: 'Start triggers and cleanup'
inputs:
azureSubscription: '${{parameters.azureSubscriptionSPN}}'
pwsh: true
azurePowerShellVersion: LatestVersion
scriptType: filePath
scriptPath: '$(Pipeline.Workspace)/datafactory/application/PrePostDeploymentScript.Ver2.ps1'
scriptArguments:
-armTemplate $(Pipeline.Workspace)/datafactory/application/arm-parameters-${{lower(parameters.Stage)}}.json
-ResourceGroupName ${{parameters.resourceGroupName}}
-DataFactoryName ${{parameters.dataFactoryName}}
-predeployment $false
-deleteDeployment $true
```
