Does plotly work with Jupyterlab 4?

Hello,
I’m pretty new to plotly/dash, but I could make the “simple app example” (coming from https://dash.plotly.com/minimal-app) work with jupyterLab 4.0.10 & plotly 5.18.0. Anyway, If I try to change the way to run the dash application from:

app.run(debug=True)

to:

app.run(jupyter_mode="jupyterlab")

well, nothing happens when I execute the cell of the notebook…although I would expect another “tab” to open in jupyterlab …

Did someone successfully make it work ?

Thanks for your help
