Access to PrivateData during import module

Question

I want to download the contents of the config.xml file and save it in $PrivateDatawhen loading my module. Here is the definition line in my PSD1

# Private data to pass to the module specified in ModuleToProcess
PrivateData = @{'Variables'=@{};'Config'=$null}

This creates a hash table with two elements. 1) Variables- the second hash table that I use to store private variables for my module. 2) Config, which will contain the values ​​of the config.xml file. XML example:

<Config>
    <Foo>Bar</Foo>
</Config>

I can load xml with the following line:

$PrivateData  = $MyInvocation.MyCommand.Module.PrivateData
$PrivateData.Config = ([xml](Get-Content $PSScriptRoot\Config.xml | Out-String)).Config

It doesn't look like I can access it in my PSM1 file. I CAN wrap it in the cmdlet like this:

Function Initialize-TestModule {
    $PrivateData  = $MyInvocation.MyCommand.Module.PrivateData
    $PrivateData.Config #= ([xml](Get-Content $PSScriptRoot\Config.xml | Out-String)).Config    
}

But then the user would have to call on Import-Module, and then a second call Initialize-TestModule, which I am trying to avoid.

If I put the code in PSM1, it generates this error when I call Import-Module

Property 'Config' cannot be found on this object; make sure it exists and is settable.

If I try to download to PSD1, like this:

PrivateData = @{'Variables'=@{};'Config'=([xml](Get-Content $PSScriptRoot\Config.xml | Out-String)).Config}
