Unable to setup kubectl-trace on azure kubernetes cluster

I tried to setup this on a azure kubernetes cluster. After installing everything when I restarted the cloud shell, everything was gone. When I typed "kubectl krew" or "kubectl trace" its showing unkown command. So I reinstalled, then its showing "skipping already installed".

For "Pre built binaries" and "Go module" commands its showing permision denied.

When I tried running against a pod. Its showing "caturday cannot be found".

Can you please tell me where I am going wrong?
TIA.
