Dear Sophie,
Good day!
Thank you for posting to Microsoft Community. We are glad to assist.
I dis some test from my new Teams. Unfortunately, the small toolbar is not available and the keyboard shortcut Ctrl+Shift+Spacebar no longer works in the new Teams. Instead, there is a shareing pane shows up when click on the Share button or use the shortcut key Ctrl+Shit+E.
