Hello Aayu,

1. You need to have a userrole admin or an equivalent (system > security)

2. You need to have moduleroles in the module where you create your page (module > security)

3. connect your admin userrole with the module userrole (system > security)

4. create your page 

5. add to the visibility properties of your page the admin modulerole

6. Or you can add it by going to module > security > pages

Hope this helps

Good luck!

Assuming you already created your module roles and configured the security properly (module role is checked for the admin user role in the app security), you can just edit the 'properties' > 'navigation' > 'visible for' of the page to be visible for the admin (right click or double click on the outer container of a page and select properties or just use the properties pane). Keep in mind the security of entities in your app.
