Run PowerShell Core scripts on Universal Forwarder

Is there a native way to run scripts in pwsh.exe managed environment?

It's not mentioned in docs so I believe not: https://docs.splunk.com/Documentation/Splunk/9.3.1/Admin/Inputsconf

We all know there is [powershell://<name>] in inputs.conf to run "classic" powershell scripts. Actually, it runs script in "classic" PowerShell environment. Depending on which Windows version/build Universal Forwarder is installed on, it will be PS version up to 5.1 (which is managed by powershell.exe binary btw).

But now we have a brand-new PowerShell Core (managed by a different binary: pwsh.exe). PowerShell Core have new features, not available in "classic" PowerShell and they're not 100% compatible. Additionally, PowerShell Core is platform agnostic - so we can install it on Linux and run PowerShell Core based scripts there (don't ask me why anyone would do that, but it's possible).

Currently I'm running PowerShell Core scripts, by starting batch script in cmd environment, then cmd starts pwsh.exe with defined parameter to run my PowerShell Core based script - not elegant at all.

At the moment there is apparently no such input type. You can always check if someone already had that idea on https://ideas.splunk.com and back it up. If there isn't one, create a new one.
