Can we use CSOM assemblies included in PnP 2.x to create anonymous share link?

[NiuBClass666]

Issue

Using the CSOM method CreateAnonymousLink in Powerhsell 5.1 with credentials(username/ps) was the way we used until the recent major update of PnP Module which obviously also upgraded the CSOM assemblies it includes. Now PnP 2.x needs to run in Powershell 7.2.x or later and it did not have Microsoft.SharePoint.Client.SharePointOnlineCredentials anymore. So we can't use Microsoft.SharePoint.Client.ClientContext to create anonymous link without a credential (Using PsCredential object as a replacement returns 403 Forbidden). Still trying to find an alternative way to do it in powershell 7 through PnP Module.

Attempt

I do not find any new PnP cmd that can create anonymous share link for an item. So we still need to use CSOM Assemblies like Microsoft.SharePoint.Client.dll and Microsoft.SharePoint.Client.Runtime.dll in PnP 2.x which are probably .net standard20 version. And my current assumption is that we need to use another authentication way like Azure AD OAuth based approach here: https://www.c-sharpcorner.com/article/sharepoint-csom-for-net-standard/

Update and Solution

It turns out we can still use the old way to create anonymous link. We just don't need to create a new Microsoft.SharePoint.Client.ClientContext after Connect-PnPOnline, so we don't need Microsoft.SharePoint.Client.SharePointOnlineCredentials or any other way to pass Credentials into this new client context. Instead using Get-PnPContext gives us the context that already has the credentials.

What we had:

    ##Connect through PnP
    Install-Module -Name "PnP.Powershell" -Force
    $username = ""
    $password = (ConvertTo-SecureString -String "" -AsPlainText -Force)
    Add-PnPStoredCredential -Name https://[your_Domain].sharepoint.com/ -Username $username -Password $password
    Connect-PnPOnline -Url "https://radiantvs.sharepoint.com/sites/DevBuilds"
    
    ##Creat Link
    $ctxClient = [Microsoft.SharePoint.Client.ClientContext]::new("https://[your_Domain].sharepoint.com/")
    $ctxClient.Credentials = [Microsoft.SharePoint.Client.SharePointOnlineCredentials]::new($username,$password)
    $link = [Microsoft.SharePoint.Client.Web]::CreateAnonymousLink($ctxClient,$itemUrl,$false)
    $ctxClient.ExecuteQuery()
    $InstallerUrl = $link.Value.toString()

What we use now:

    ##Connect through PnP
    (same)

    ##Creat Link
    $ctxClient = Get-PnPContext
    $link = [Microsoft.SharePoint.Client.Web]::CreateAnonymousLink($ctxClient,$itemUrl,$false)
    $ctxClient.ExecuteQuery()
    $InstallerUrl = $link.Value.toString()
