For event https://indico.cern.ch/event/661919/ we would like to restrict access to the contribution material (i.e. the presentations) to the participants. I know I could modify the access rights to the individual presentations (no too many, it’s feasable manually) but I don’t think I can create a new group with all the participants of that particular event, and adding all 62 participants indivdually to each single contribution is not feasable.
Is there a way to achieve this? All participants have a role (“Speaker”), maybe this can be used to give them access to the contribution material?
