@mentions roadmap confusion

Hi,

according to roadmap feature ID https://www.microsoft.com/de-ch/microsoft-365/roadmap?filters=&searchterms=mentions the feature @mentions in Win32 has supposedly been launched.

There's no mention except for Word https://support.office.com/de-de/article/use-mention-in-comments-to-tag-someone-for-feedback-644bf689-31a0-4977-a4fb-afe01820c1fd?ui=de-DE&rs=de-DE&ad=DE and in the change log for Vhttps://docs.microsoft.com/en-us/officeupdates/monthly-channel-2018#version-1808-september-5

Has anyone noticed that this is available in the Office desktop apps Word, Exel and PowerPoint yet?

Thanks.
