Thanks you so much for advising.

As its navigational flow , need to do query selector for for getting
element to click or inputting the values.

If we assigned to type of TextPage or Page , not able to do query selector
with methods "page.querySelectorAll", for same we need type HtmlPage at the
end in the navigational clicks or submission.
