How to insert two nodes at once?

// Replacing with a image node which uses a url 
view.dispatch(view.state.tr.replaceSelectionWith(newNode));

let attrs = {
        title: node.text, // node.text is the URL
        href: node.text,
        target: '_blank',
      };
      let linknode = view.state.config.schema.nodes.paragraph.create(
        view.state.config.schema.marks.link.create(attrs),
      );
      
      // This is not inserting anything. Requirement is to place a url below the newNode with "_blank" target.
      view.dispatch(view.state.tr.replaceSelectionWith(linknode));
      view.focus();

How do I insert a link using a text with target _blank immediately after inserting below a node?

You can group multiple changes in a single transaction, if that’s what you’re asking. Just call the transaction methods (in this case replaceSelectionWith) on a single transaction and then dispatch that once.
