Parameter 'PhysicalPath' should point to existing path, on Azure File Share

[sprashanthkumar]

I am trying to create a webApplication on IIS pointing to Azure File share using PowerShell DSC xWebApplication as below
xWebApplication AppName
{
DependsOn = "[xWebSite]xWebSiteName"
Name = "appname"
PhysicalPath = "\azurefileshare\etc"
WebAppPool = $AppPoolName
Website = $WebSiteName
}
I am getting "Parameter 'PhysicalPath' should point to existing path." error where the mentioned path can be accessed manually and able to set to IIS application manually.
All the user accounts involved in the process have full control access on file share
Also observed in Process Monitor that PowerShell DSC kicks off "C:\windows\system32\wbem\wmiprvse.exe" running as NT AUTHORITY\SYSTEM and not sure how to change user when running th PowerShell DSC.

Can someone help in this regard please.

Consider using built-in parameter PSDscRunAsCredential to change what user the resource is run as.

@johlju apologies for not getting back sooner, I am having issue including PSDscRunAsCredential which I am trying to figure out,
besides just to trim down the issue, I tried creating an application using Invoke-Command with credentials which giving Bad network error.

I will update on PSDscRunAsCredential

after adding below scripts
$ConfigData = @{
AllNodes = @(
@{
# The name of the node we are describing
NodeName = "$Computer"
PSDscAllowDomainUser = $true
};
);
}
and below in configuration
Registry CmdPath
{
Key = 'HKEY_CURRENT_USER\SOFTWARE\Microsoft\Command Processor'
ValueName = 'DefaultColor'
ValueData = '1F'
ValueType = 'DWORD'
Ensure = 'Present'
Force = $true
Hex = $true
PsDscRunAsCredential = Get-Credential
}
I am getting this error:

going through : https://docs.microsoft.com/en-us/powershell/scripting/dsc/pull-server/securemof?view=powershell-7.1
