Extension that write in cell (jupyterlab4)

I need to migrate extension code from jupyterlab3 to jupyterlab4, but I don’t manage to adapt this code:

jupyterlab-contrib/jupyterlab-tour/blob/4b49b83c20fae56ad45c21dee8d1591f6c320cef/src/defaults.tsx#L446


      
          case '.jp-NotebookPanel-toolbar .jp-Notebook-toolbarCellType':
            {
              if (nbTracker) {
                currentNbPanel = nbTracker.currentWidget;
                if (currentNbPanel && !addedCellIndex) {
                  const notebook = currentNbPanel.content;
                  NotebookActions.insertBelow(notebook);
                  const activeCell = notebook.activeCell;
                  addedCellIndex = notebook.activeCellIndex;
                  if (activeCell) {
                    activeCell.model.value.text = 'a = 2\na';
                  }
                }
              }
            }
          
            break;
          case '.jp-NotebookPanel-toolbar .jp-KernelName':
            shell.activateById('jp-running-sessions');
            break;
          case '#jp-running-sessions':

In jupyterlab4, activecell no longer has the property ‘value’

I tried with activeCell.editor but I can’t find how to do it.

I changed to

activeCell.model.sharedModel.setSource('a = 2\na');

it seems to work
