This processor checks whether an element exists. When swapping tokens, an “Approve” button appears if approval is required. You’d click Approve and then sign the transaction in Rabby or Metamask. If the button doesn’t appear, there’s no need to sign the approval transaction. The Element Exists processor fits perfectly for handling this logic.
