Set page numbering format and counter from template

Questions
1

I generate my books using mdbook-typst and have a nice template for my project:

#let template(
  title: [Book title],
  author: "Author",
  paper-size: "a5",
  dedication: none,
  publishing-info: none,

  body,
) = {
  set document(title: title, author: author)
  set text(font: "Libertinus Serif")
  set page(
    paper: paper-size,
    margin: (bottom: 1.75cm, top: 2.25cm),
  )
...

I would like to set the page numbering format and counter from that template so that every time I generate a book, it get it right.

To achieve the result, at the moment, I have to insert manually:

#set page(numbering: "i")
#counter(page).update(1)

before my introduction in my .typst main document and:

#set page(numbering: "1")
#counter(page).update(1)

before the first part of the book.

I have tried to play around with the rules, such like:

set page(
    
    footer: context [
      
        #set align(center)
        #let (num,) = counter(page).get()
        #let p = here().page()
        #let allLevel1Heading = query(selector(heading.where(level: 1)))
        #let firstPage = allLevel1Heading.at(0).location().page()
        #let secondPage = allLevel1Heading.at(1).location().page()
        #let thirdPage = allLevel1Heading.at(2).location().page()
           
        #if (p > firstPage + 1 and p < secondPage - 1){
            counter(page).display("i")
        }        
        #if (p > secondPage and p != thirdPage){
            counter(page).display("1")
        }        
    ]
  )

And adding rule to reset the counter, but I realized that it is impossible to reset the counter from the template alone. Is there another solution ?
