US Patent 12019775 Managing permissions for collaborative shared documents

Media, methods, and systems are disclosed for managing permissions for a collaborative document within a group-based communication system. A collaborative document may be created within a group-based communication system. When the collaborative document is created, permissions may be automatically assigned based on the context of collaborative document creation, such as which virtual space the collaborative document creation corresponds to. After creation, the collaborative document may be shared and permissions may be automatically updated based on the sharing context. Users without appropriate permissions will be prevented from accessing the document.
