Unable to connect/run on PowerShell 7

When trying to run the script on a PowerShell 7 system using either a pre-made App registration or just the default, I get the error message that Connect-MSGraph can't load a type, which means the connection doesn't get started and all else just fails horribly:

$tenant = 'tenantid'
$appid = 'appid'
$secret = 'secret'

Invoke-IntuneDocumentation `
    -FullDocumentationPath c:\temp\IntuneDoc.docx `
    -ClientId $appid `
    -ClientSecret $secret `
    -Tenant $tenant

The exact same happens when running

A little bit of digging shows that this seems to be a Connect-MSGraph related issue on PS "core" edition as you can find here.

$psversiontable

Running the exact same code under Windows PowerShell works just fine.

$psversiontable

SerializationVersion           1.1.0.1

Suggestion is to either update documentation that Windows PowerShell is required or perhaps another solution/workaround for this issue.
