"@thread.tacv2_wiki" file in recent documents of office.com portal after creating new wiki page

And this is what it looks like if I open it:

Does anyone have an idea why this file is appearing here?

@JUNFS It's where the wiki is stored, a generally hidden library in the SharePoint site.

Leave it alone :)
