How to use the @jupyter-widgets/base.put_buffers function in @jupyter-widgets/base

comm.on_msg((msg) => {
          put_buffers(msg.content.data.state, msg.content.data.buffer_paths, msg.buffers);
          // A suspected response was received, check to see if
          // it's a state update. If so, resolve.
          if (msg.content.data.method === 'update') {
            resolve({
              comm: comm,
              msg: msg
            });
          }
        });
      });

comm.on_msg(function (msg) {
                            base.put_buffers(msg.content.data.state, msg.content.data.buffer_paths, msg.buffers);
                            // A suspected response was received, check to see if
                            // it's a state update. If so, resolve.
                            if (msg.content.data.method === 'update') {
                                resolve({
                                    comm: comm,
                                    msg: msg
                                });
                            }
                        });
                    });

comm.on_msg(async (msg) => {
                base.put_buffers(msg.content.data.state, msg.content.data.buffer_paths, msg.buffers);
                if (msg.content.data.method === 'update') {
                    resolve({comm: comm, msg: msg});
                }
            });
            comm.send({method: 'request_state'}, {});
