Here’s how to copy a sequence from your chatbot
To duplicate a sequence in your chatbot to modify it or simply copy it to another group, simply click on the “copy” icon displayed in the header of your sequence.

A second, completely identical sequence with the same name and (copy) extension is then generated in your group.
Before :

After

You can then edit the new sequence or move it to another group.
You can duplicate as many sequences as you like, as many times as you like 😉
