Below is the summary as how I made Kubelogin worked for my AKS Cluster.

1. Installed Kubelogin using choco :- choco install kubelogin

2. AKS uses kubelogin plugin for authentication :- kubelogin convert-kubeconfig -l azurecli

Below was the error encountered -

error: unknown shorthand flag: 'l' in -l

3. Uninstall kubelogin using choco :- choco uninstall kubelogin -y

4. Install kubelogin using Azure Github: https://azure.github.io/kubelogin/install.html

winget install --id=Microsoft.Azure.Kubelogin -e

5. Validate Version : - kubelogin --version

Below is the output -
