function New-AzRemediationTasks { <# This PowerShell script creates remediation tasks for all non-compliant resources in the current Azure Active Directory (AAD) tenant. The New-AzRemediationTasks.ps1 PowerShell creates remediation tasks for all non-compliant resources in the current AAD tenant. If one or multiple remediation tasks fail, their respective objects are added to a PowerShell variable that is outputted for later use in the Azure DevOps Pipeline. Defines which Policy as Code (PAC) environment we are using, if omitted, the script prompts for a value. The values are read from `$DefinitionsRootFolder/global-settings.jsonc. Definitions folder path. Defaults to environment variable `$env:PAC_DEFINITIONS_FOLDER or './Definitions'. Set to false if used non-interactive Include non-compliance data only for Policy assignments owned by this Policy as Code repo Filter by Policy definition names (array) or ids (array). Filter by Policy Set definition names (array) or ids (array). Filter by Policy Assignment names (array) or ids (array). Filter by Policy effect (array).
