Can codeEditorWrapper objects save via Command s?

JupyterLab extensions
1

I’m building an extension and I have a code editor object:

        const editorFactory = (options: CodeEditor.IOptions) => {
          options.config = {
            lineNumbers: true
          }
          return new CodeMirrorEditor(options);
        };

        let model = new CodeEditor.Model();
        let content = new CodeEditorWrapper({model, factory: editorFactory});
        let widget = new MainAreaWidget({content});

Right now, when this code editor is visible on JupyterLab, I can’t save it like a file via Command s. This error: Cannot execute key binding 'Cmd S': command 'docmanager:save' is not enabled. shows up. Is there any way I can enable it? Thanks.
