Hello All,
I work with California Department of Fish and Wildlife and we are working on creating a series of range maps for imperiled species across the state. Part of this process is getting external expert reviewers to give their feedback on the maps we create. Our ranges are based on a polygon layer that intersected HUC12s and USDA Ecoregions; which gives us a series of polygons to light up to build the ranges. So I created a Experience that would allow reviewers to edit copies of the ranges and change the status of each polygon marking it for deletion, possible deletion, inclusion, and so on. (The image below may illustrate this better.)

We were wondering how we could share this experience with the expert reviewers and not have the information become public? And/or we do not want the reviewers to have access to other data in our organization aside from the experience and the specific layers they are editing.
