App + User authentication and Project Online development

Hi There,

The last bit of code, how can I do this in powershell. I have managed to get an access token with Powershell commands.

csom.ProjectContext psCtx = new csom.ProjectContext(pwaInstanceUrl);
            psCtx.ExecutingWebRequest += (s, e) =>
            {
                e.WebRequestExecutor.RequestHeaders["Authorization"] = "Bearer " + TokenResult.AccessToken;
            };

I now need to connect to the project context using similar code to below but use the token instead of user/password. Microsoft.SharePoint.Client.SharePointOnlineCredentials does not provide the authentication in an Azure function as it does when run from desktop?

$ProjCtx = New-Object Microsoft.ProjectServer.Client.ProjectContext($siteURL)

[Microsoft.SharePoint.Client.SharePointOnlineCredentials]$spocreds = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.UserName, $Cred.Password);
$ProjCtx.Credentials = $spocreds
