Search Deleted Tasks from All members in Workspace

Hi,

We are using the ruby-asana gem; quite satisfied with it and have also included our own contributions.

I found in another thread that it’s possible to search for deleted tasks here Help! Permanently deleted a task! Can I restore?

When I perform this search, I only see tasks that have been deleted by me, and I presume that will also be the case when I use the search API that uses my personal access token. How can I - if even possible - query for all deleted tasks with a set of projects that all live under one workspace? Returning just mine isn’t useful. Does the access token need to be the owner/admin of the workspace?

Thanks in advance.
