Permanently delete more than 20.000 work items from Azure DevOps recycle bin

The problem is not to destroy a specific work item. The problem is how to figure out, which work items (or ids) are in recycle bin.

I have implemented the following work around now:

I delete all work items which are within a given range of startWorkItemId and endWorkItemIf, and ignore all failed delete operations. This approach works quite well, but is very slow if the range is huge.
