Connect to MySQL on GCE using Google Colaboratory

I am trying to access MySQL on GCE VM instance through Google Colaboratory though, unfortunately, it does not work properly but does work in the local VSCode environment.

While executing TestExec.py, it shows SSH Connected so it seems that ssh connection is successfully done though, however, it seems to be stuck on MySQL connection.

Output on Google Colab:

Please help with the solutions/tips?
