I have used this extension extensively in the months of testing. It works as advertised and is the ONLY current solution to the disconnects from the Google Colab service. I would highly recommend this and other of Teal's add-ons/extensions.
A thing i want to tell you it do not able to connect and run all the colab pages but any few some time it connect some pages but do not able to run the first cell other things are fine
