Why is my script not running automatically when outlook is started?

问题

This script is in ThisOutlookSession and is only running if I change the functions to Public and run the function manually. I am using Outlook 365. This program scans for emails in an Inbox subfolder and when a new email comes in it downloads the attachment and sends it in an email to a different address. Why is it not running automatically and how do I fix it?

Option Explicit
Private WithEvents Items As Outlook.Items
Private Sub Application_Startup()
    Dim olNs As Outlook.NameSpace
    Set olNs = Application.GetNamespace("MAPI")

    Dim Inbox  As Outlook.MAPIFolder
    Set Inbox = olNs.GetDefaultFolder(olFolderInbox)
    
    Dim Sub_folder  As Outlook.MAPIFolder
    Set Sub_folder = Inbox.Folders("DocuSign")
    
    Set Items = Sub_folder.Items
End Sub

Private Sub Items_ItemAdd(ByVal Item As Object)
