Need help in executing powershell commands in dockerized laravel – Phpmyadmin

I want to access vsphere config info from powercli script to laravel. But I do not know how to make them work together in docker. Whatever I do, the error is similar to this – The command "’pwsh’ ‘-v’" failed. Exit Code: 127(Command not found) Working directory: /var/www/public Output: ================ Error Output: ================ sh: 1: exec: pwsh: not found
As a last resort, I am here.

docker-compose.yml:

Controller:

//$process = new Process(['ls', '-lsa']); #This works but next one do not
$process = new Process(['pwsh', '-v']);
$process->run();
// executes after the command finishes
if (!$process->isSuccessful()) {
       throw new ProcessFailedException($process);
}
echo $process->getOutput();

I know how the Process() method works. Above code fails.
I need help on making powershell and laravel work together in docker.
Is there anything wrong with docker configuration or the controller code in accessing powershell.
