Hi @41844108 ,
According to your description, you should have created a Wiki Page directly in the Pages library and published it.
After the Page is published, a major version (that is, the current version) will be generated and appear in this library. When you open it again, it is the content of the latest published page.
As for adding a tab in Teams, you cannot directly add a Wiki Page. Because it currently supports modern pages.
Wiki pages are classic, you can directly add the library that contains this Wiki page to the tab.
If you want to see only Wiki pages, you can create a view that contains only Wiki pages.
