How can I retreive a lesson that i have deleted accidentally?

Hi everyone! We've improved the visibility and functionality of the undo notification that appears when you delete blocks and lessons.

The new undo notification appears for 12 seconds with a timer indicator. If you need longer than 12 seconds, hover your mouse over the notification to pause the timer. You'll also see multiple notifications when more than one block is deleted.

Let us know if you have any questions about this enhancement!
