How can I programmatically switch to sqlite.ipynb panel? Also how can I get which panel is currently active? thanks:)

One of many ways is by executing command tabsmenu:activate-by-id, at least this is what I used in ui-profiler

jupyterlab/ui-profiler/blob/7544e7484305950fb411b1324c1dd1fa6039cf2d/src/scenarios.ts#L471-L483


      
          async function activateTabWidget(
            jupyterApp: JupyterFrontEnd,
            widget: MainAreaWidget
          ) {
            await jupyterApp.commands.execute('tabsmenu:activate-by-id', {
              id: widget.id
            });
            await layoutReady();
            await page.waitForSelector(`li.lm-mod-current[data-id="${widget.id}"]`, {
              state: 'attached'
            });
            await layoutReady();
          }

also see the command list Commands — JupyterLab 4.1.0a3 documentation although the arguments are not currently documented.

Also how can I get which panel is currently active?

Generally widget trackers (e.g. INotebookTracker) and JupyterFrontEnd.shell this is ILabShell have .currentWidget attribute and the latter also has .activeWidget.
