No animation control widgets in Jupyterlab

Describe the issue

Funcanimate does not display animation control widgets in Jupyterlab

It would be possible to implement them by hand using buttons, widgets, and the resume and pause functions but functionality to "seek" is not documented (not available?).

Inizia riproducendo Funcanimate nell’ambiente JupyterLab indicato e verifica come si comportano le funzioni resume e pause esistenti. L’attività è completata quando in JupyterLab sono disponibili widget per il controllo dell’animazione e il comportamento seek richiesto da questo issue è documentato o chiarito.
