Excel Document-level customization - Setting width of Action Pane (VB.net 4.8)

I am trying create a simple Action Pane Control in a Document-level VSTO, writting in VB.Net. [.net 4.8]

With the code I have now I open the Action Pane on Sheet1 and hides it on other sheets.

The issue I can't find a solution to is to set the width of the action pane and its control - It is simple to narrow as default.
Every time the workbook is opened, the action pane opens with the default widt, so every single time you have to start out by resizing the action pane. That is an annoyance.

Example image:


Every topic I have found on this refers to setting the width as this ( link: actions-pane):

Me.CommandBars("Task Pane").Width = 200  


Application.CommandBars("Task Pane").Width = 200  

My code for sheet1:
(apcWareList is the Action Pane Control)

 Imports Microsoft.Office.Interop.Excel  
    Public Class Sheet1  
        Private tpWareList As New apcWareList  
Private Sub Sheet1_Startup() Handles Me.Startup  
            Application.CommandBars("Task Pane").Width = 500  
            Globals.ThisWorkbook.Application.DisplayDocumentActionTaskPane = True  
        End Sub  
        Private Sub Sheet1_Shutdown() Handles Me.Shutdown  
        End Sub  
        Private Sub Sheet1_Deactivate() Handles Me.Deactivate  
            Globals.ThisWorkbook.Application.DisplayDocumentActionTaskPane = False  
        End Sub  
        Private Sub Sheet1_ActivateEvent() Handles Me.ActivateEvent  
            Globals.ThisWorkbook.Application.DisplayDocumentActionTaskPane = True  
        End Sub  
    End Class  

Anyone who can spot my error?

    If I throw in this line:

       MsgBox(Application.CommandBars("Task Pane").Name)

    I get a prompt with the text "Document Actions", which funny enough is the one I need to update the width of..

    But the line from any documentation states that Application.CommandBars("Task Pane").Width = 800 should update the width. Which is not happening.

    Is there any settings in Visual studio that needs to be corrected? any imports that must be included?
