Trouble running PowerShell command with subprocess library in Python script runbook (Azure automation account)

Question

I'm new to Azure automation, and have a python script that runs fine on the local machine. The script runs a PowerShell command to get sign in logs, and does some string parsing on them before writing to a storage account table. I was able to install all dependencies for the script via the "Python Packages" blade in the automation account. Is there a way to add powershell.exe somewhere so that the subprocess library can be used to run the PowerShell command? Alternatively, is there a library you can import to be able to run the PowerShell command or grab sign in logs from Azure AD without directly using the powershell.exe file?

Am I just using the wrong filename and should use something other than powershell.exe? Is there a different module you have to install, or am I referencing it wrong?

import subprocess
import sys
import json
import azure.core
from azure.core.credentials import AzureNamedKeyCredential 
from azure.data.tables import TableServiceClient, TableClient 

data = subprocess.check_output(["powershell.exe", "Connect-AzureAD -AccountId placeholder@placeholder.com \n Get-AzureADAuditSignInLogs"]).decode(sys.stdout.encoding)
