`No provider for: @jupyterlab/notebook:INotebookTools` in notebook, but not in lab

JupyterLab

Hello.
Here is a simple plugin

import { JupyterFrontEnd, JupyterFrontEndPlugin } from "@jupyterlab/application";
import "../style/index.css";
import { INotebookTracker } from "@jupyterlab/notebook";


/**
 * Initialization data for foo extension.
 */
const plugin: JupyterFrontEndPlugin<void> = {
  id: "foo:bar",
  description: "A JupyterLab extension.",
  autoStart: true,
  requires: [INotebookTracker],
  activate: async (app: JupyterFrontEnd, notebookTracker: INotebookTracker) => {
    app.started.then(async () => {
      console.log(notebookTracker.activeCell);
    });
  }
};

export default plugin;

It works with jupyter lab but for jupyter 7 (running from the same environment) it says:

TypeError: No provider for: @jupyterlab/notebook:INotebookTools.

Should I file a bug?

Fixed by installing notebook explicitly
