I am using some Lexial plugin that enhances the copy/paste experience (CopyPasteEnhancementPlugin).

When investigating how it works I found this helper function inside clipboard.ts. The function gets called each time the user pastes some content into Lexical:

export function $insertGeneratedNodes(
  editor: LexicalEditor,
  nodes: Array<LexicalNode>,
  selection: BaseSelection,
): void {
  if (
    !editor.dispatchCommand(SELECTION_INSERT_CLIPBOARD_NODES_COMMAND, {
      nodes,
      selection,
    })
  ) {
    selection.insertNodes(nodes);
  }
  return;
}

I need to intercept the nodes before they get inserted into the selection. E.g. I want to transform the text so all   get replaced with " ". Or certain words get replaced with some arbitrary text string and so on.

What would be the correct way to do this?
