What version of Office client is required for Teams to have full functionalities/best UX?

Nothing is mentioned in the pre-requisites, yet I read that without ProPlus you can't co-author on files stored in Teams (SharePoint) because the Office apps must be authenticated with O365. Without that co-authoring is only possible in the browser

 

EDIT:

Just found this bit:

For Word - You'll still be coauthoring, as long as you're an Office 365 subscriber, using one of these versions of Word:

  • Word 2016 for Windows
  • Word 2016 for Mac
  • Word on a mobile device (Android, iOS, or Windows)

If you're using an older version of Word, or if you're not a subscriber, you can still edit the document at the same time others are working in it, but you won't have real-time collaboration

 

For Excel however "You need the latest version of Excel for Office 365 installed"
