Monitoring progress bar not showing when using spark on kubernetes kernel

[meenakshi123]

I am trying to use sparkmonitor for monitoring my spark job which i am running on jupyterlab and spark on kubernetes kernel.It works fine when i am using python3 kernel.

In logs i can see that extension is loaded fine and some other info.

INFO:SparkMonitorKernel:Starting Kernel Extension
INFO:SparkMonitorKernel:Socket Listening on port 33039
INFO:SparkMonitorKernel:Starting socket thread, going to accept
INFO:SparkMonitorKernel:33039

My jupyterlab version is 3.5.0 and spark on kubernetes is 3.0.2

Can someone please help me on this.
