Go to the “Users” module.

Open the “Pages Permissions” page.

Choose the name of the user or group of users whose permission you want to change.

Click on "＋" to access the page whose permissions you want to modify

Double-click on the page on which the specified user has permission to view all the details of the page (in principle, the user gains authority over all page controls once he gains authority over the page)

Modify the permissions to be modified by pressing “▢” (for example, revoke the permission on the edit button and the delete button)

Choose the type of permission to be revoked/granted to the user on the page details (Visible – Enabled)

Press “Save”
