Group Calendar for Teams
Is it possible to create a group calendar in Teams where members can create events and then have a tab at the top where team members can easily access this calendar?

You can add a Website tab to a channel and have the tab pointed to a SharePoint calendar. It isn't the greatest experience (essentially iframing a SharePoint Calendar page), but it works.

... plus the option to link ReadOnly to that Team calendar from any other web page, something like viewing a Sharepoint calendar (but without any menus, headers and other buttons, just "see" the calendar).
