The user guide for page customizations at https://dev.liferay.com/discover/portal/-/knowledge_base/6-2/page-customizations starts with the following sentence:
"Administrators can designate public pages or sections of public pages to be customizable."
Which seems to imply that this functionality is only available for public pages.
However, according to my recent tests on LPP-20423, it can be used also for private pages, and I can also not see why it shouldn't be designed also for private pages.
If that is indeed the case, shouldn't this sentence be modified so as to not imply that this feature is designed only for public pages?
