Create a Resource record as you normally would, paying special attention to the fields described below. For detailed instructions on this topic, see the linked document: Create Resources to Support Learners and Enhance Training Programs.
Create a new Self-Study Course to house the link to your hidden resource. By making this an “Approval Required” course, you can then restrict resource visibility to users with manager-approved enrollments only.
There are multiple ways to restrict course visibility and access rights. Using an approval-required course to house sensitive content is the most restrictive, ensuring that a supervisor has manually approved every user’s access.
However, you could utilize other LMS features to automate the approval process and enforce a more “hands off” restriction. For examples and instructions on configuring alternative enrollment eligibility rules, see related document: Restrict Course Visibility and Enrollment Dates.
