Redwood VBS Advanced Mode for Self service procurement for My receipt page

We are trying to call a report from My Receipt - Redwood page, and i found the below link , using which we can call the report.

But, currently the components fields while using the VBS - Advance Mode Page Designer to add the button is Greyed out, due to which we cannot add a button on a My Receipt Page.

Can we add the button using some other way, or is there any other way to call the custom report from the page.

Appreciate your feedback on the above.
