As an admin, you have a few options when deciding to hide or show resources to your users.

By setting resources so that 'Only admins can book', you are able to hide resources from your users' workplace mobile app. This way, you will have control over the schedule of bookings and who has access. You can make these updates from the booking policy of any resource.

You can also edit Resource Types and specify whether you want resources assigned to a type to appear in the mobile app, or if you'd like them to be hidden. You can edit a resource type from the Resources > Resource Types page.
