Is debugging available in Jupyter-lab for Sagemath ?

edit

Hello everyone,

In Jupyter-lab, I can activate the debugger for python kernel by clicking on the little bug icon, ant it works fine. But for sagemath kernel, the bug can't be activated, and I have the following message : "Select a kernel that support debugging to enable debugger". So my question is simple : does sagemath jupyter kernel support debugging or am I doing something wrong ?

Thank you for any help
