@Sebastian Pacheco I don't know how that works from inside Cloud Shell, but I'd suggest downloading kubectl and connecting to AKS from your machine, you'll have a lot more control and overall better experience than using a cloud shell.
@Sunilkumar S Assuming you're using kubectl from your local machine, you'll need to install kubelogin and execute the conversion, which will switch the deprecated authentication method to a newer one. Unfortunately that GitHub repository doesn't explain it very well, so I tried my best to explain in depth how it works and to remove the deprecation in this article https://aptakube.com/blog/how-to-use-azure-kubelogin
