Exporting environments from a team workspace

How can I export environments from a workspace other than my own? My team has a workspace with hundreds of environments, and sharing them one by one is not feasible, so I am trying to export them so they can be imported into a new workspace.

I have used the export tool as described here multiple times, but I have not found a way to export the environments from any workspace other than my personal one.

There does not seem to be a way in the UI to choose which set of environments to export, and if I navigate to Settings > Data from the team workspace rather than my personal workspace to begin the export, it does not seem to matter.
