The 5.9.13 firmware includes a Teams client build from April 8th, 2020 (the new Teams features were originally added in the March 19th build). I've been running this new version on a few CCX phones at home for a month now and it is a huge improvement.
Be aware though that the newest Teams client still has a issue (which Microsoft plans to fix) which currently requires you to sign out of the client and sign back in after upgrading it as not all of the new client features will appear post upgrade. For example you'll see the 'Manage Delegates' menu and also see the new Ringtone options after the phone reboots post-upgrade, but the Calls screen will not display the new Favorites layout until signing out/in.
