Hello, I am trying to allow users to be able to change information previously extracted in the conversation at any given time/node. I am not sure how to achieve this. What I tried was making the extract variable nodes into global nodes, but that does not seem to work because I am unsure how to jump back to the previous node, the one where the global node was triggered. For example, If I have the flow of nodes like: A -> B -> C -> D and I extracted the name of the user in node A with its respective extract variable node, I can be in node D and say "Oh, I forgot to give my last name" it jumps back to correct the name variable and then go back to node D and keep the conversation going naturally. How can I achieve this behavior?
