Add new trainstop in "Hire an Employee" Redwood page using VBS

Hi,

I want to add a custom trainstop in the "Hire An Employee" Redwood Page using VBS and want to add a textfield and a button which calls an External API in that custom trainstop. How will I be able to meet this requirement using VBS ?

I tried to add the textfield and button in this page only but currently all the components are disabled in VBS for this page.
