I have a need to allow customer community users access to specific files based on a field on their contact records. Is this possible? I am thinking that I could have a Library that I would add the files to that they need access. I am not seeing how to add only some of the customer community users to a public group to give them access to the library. Thoughts? I have the basic Customer Community portal licenses. If this could be done with the Customer Community Plus licenses, I would buy them. Thanks!
