How to instantly enter text after page load?

Question

Chromium

Welcome all!
There is a site and you need to make it so that when the page loads to fill in the data on sending, the data is automatically inserted there.
My following code is written in puppeteer. I tried many approaches, tried to change the value on load (nothing is inserted), searched for the selector and sent the value there (also empty fields), now my code automatically fills each field separately after loading.
Here is the code:

await page.goto("https://www.adidas.ru/delivery", {waitUntil: 'domcontentloaded'}); //Переход к оформлению
  await page.waitForXPath("/html/body/div[2]/div/div[1]/div/div/div/div[2]/div/main/form/div/div/div/div[10]/div/div/div[1]/input", {timeout: 7000});
  await page.type("input[data-auto-id='shippingAddress-firstName']", firstName); //Заполнение данных отправки
  await page.type("input[data-auto-id='shippingAddress-lastName']", lastName);
  await page.type("input[data-auto-id='shippingAddress-city']", city);
  await page.type("input[data-auto-id='shippingAddress-zipcode']", postalCode);
  await page.type("input[data-auto-id='shippingAddress-address1']", street);
  await page.type("input[data-auto-id='shippingAddress-houseNumber']", houseNumber);
  await page.type("input[data-auto-id='shippingAddress-phoneNumber']", phoneNumber);
  await page.type("input[data-auto-id='shippingAddress-emailAddress']", emailAddress);

But the task remains unresolved, how to make sure that after loading the page all the fields are already filled in there at once?
