Enable Custom Permissions in Permission Sets

Custom permissions give you a way to provide access to custom processes or apps. After you’ve created a custom permission and associated it with a process or app, you can enable the permission in permission sets.
Available in: both Salesforce Classic (not available in all orgs) and Lightning Experience
Available in: Group, Professional, Enterprise, Performance, Unlimited, and Developer Editions

In Group and Professional Edition organizations, you can’t create or edit custom permissions, but you can install them as part of a managed package.
