When you convert a personal page to an app page, it becomes available to all users with access to the selected app.
Note: You must have the page builder role to perform this action.
To convert a personal page to an app page:
Select Page options, in the upper right of the personal page.
Select Convert to an app page. The Convert to an app page dialog displays.
Enter the Name for the converted page, and select the App it'll reside in and (optionally) the Category.
By default, the Name field displays the current name of the page. You can edit or change this as you need.
Select Publish.
The page reopens in the selected app, and a confirmation message displays in the upper right.
