Missing PSWSman module in the custom runtime

I tied using the sample code and modified it to run some commands in the remote computer using invoke-web request. Test Inoke throws the following error
{
"errorType": "PSRemotingTransportException",
"errorMessage": "This parameter set requires WSMan, and no supported WSMan client library was found. WSMan is either not installed or unavailable for this system."
}

I tried a workaround following this post https://blueleader07.medium.com/lambda-powershell-layer-15c0ec6f6d4a to replace the PSWSMan library libmi.so. I still get the same error. Does the custom runtime have all commands available like the regular Powershell version?

Thanks for looking into the issue.

Reproduce the sample's remote-command path using Invoke-WebRequest and inspect how the custom runtime packages PSWSMan and libmi.so. Compare the available commands and WSMan support with regular PowerShell; done means the runtime's supported behavior and a verified resolution or limitation are documented.
