I am looking to write a PowerShell script to retrieve the names of the approvers of manual validation tasks within azure devops pipelines.

We use ManualValidation@0 tasks within the yaml code of our release pipelines for our approvals. The names of the people who approved these pipelines are visible within azure devops itself but I cannot find a way to retrieve these using a script. Any help would be greatly appreciated.

I have attempted using a powershell script with the Azure REST API to pull the timeline of pipeline builds and have found some details about the ManualValidation@0 tasks but nothing seeming to link to the user who actually made the approval.
