Duplicate allows you to make an exact copy of a Topic. To duplicate a Topic, click on the ⋮ icon in the right margin and then click Duplicate.

All the blocks in the Topic will be duplicated.

ℹ️ A task that appears in a meeting is just a link. If you duplicate a Topic that contains a task, it is therefore a link to the original task that is duplicated (not the task as with the Duplicate Task feature).
