When adding collaborators as 'view only', they are still able to edit the content. I want to add collaborators as view only so that they can interact with the activities to see how it works, but not have the authority to edit the content. I also tried doing a shareable link, but that link only allowed downloading and exporting. Is there another way to share the content so that people can interact with the activities? I don't want to have them download and upload the files separately onto Lumi.
