[BUG] New-PnPSite using -HubSite parameter returns System.UnauthorizedAccessException

[Nazul]

Issue

Using: New-PnPSite -Type CommunicationSite -Title '<SiteTitle>' -Url 'https://<tenant>.sharepoint.com/sites/<siteAlias>' -Description '<Description>' -Lcid '1033' -HubSiteId '<Guid>' -Connection $connectionVariable

Fails with this exception: New-PnPSite: {"error":{"code":"-2147024891, System.UnauthorizedAccessException","message":"Attempted to perform an unauthorized operation."}}

However, by doing this:

$newSite = New-PnPSite -Type CommunicationSite -Title '<SiteTitle>' -Url 'https://<tenant>.sharepoint.com/sites/<siteAlias>' -Description '<Description>' -Lcid '1033' -Connection $connectionVariable
Add-PnPHubSiteAssociation -Site $newSite -HubSite '<HubSiteUrl>' -Connection $connectionVariable

Works without error.

This fails running it locally using both, Windows PowerShell 5.1, PowerShell 7.2 and also using Azure Functions (Windows, runtime 4 with PowerShell 7.0, 64-bit).

Expected behavior

New-PnPSite with -HubSite parameter creates a new site associated with the matching hub site.

Actual behavior

Fails with this exception: New-PnPSite: {"error":{"code":"-2147024891, System.UnauthorizedAccessException","message":"Attempted to perform an unauthorized operation."}}

Steps to reproduce behavior

1. Create a new connection to SharePoint admin, using a SharePoint administrator account, via $connectionVariable = Connect-PnPOnline -Credentials $credential -Url https://<tenant>-admin.sharepoint.com -ReturnConnection
2. Use New-PnPSite with -HubSite parameter trying to create a new site that will be associated with an existing hub site
3. Exception is received, and site is not created
