Shared calendars now sync to mobile phones

Does this include the ability to open a colleague's calendar? This has been a huge gap in the apps for years - really hope it can be added for Outlook for iOS/Android: go to settings, open shared calendar, type in the name of the individuals name and if you have permissions, it opens - just like on Outlook. My users have been asking for this for a long time.
To echo comments below -shouldn't have to be reliant on this invitation exclusively as a result of this new update, but based on the existing permissions that have (in some cases) been in place for years, just relegated to desktop versions of Office (or a web browser).

Thanks!
