Help to find Dynamic xpath

Question

Good evening guys, I’m having a hard time finding Dynamic xpath in the email and login part of the nike.com.br website, I’ve tried several extensions, but the xpath they find always change when they refresh the page.

• Buttons I need the Dynamic xpath: https://prnt.sc/y73k3v

I have tried to do in many ways the mistakes consist of:

Failed to execute 'querySelector' on 'Document, (... is not a Valid selector)

and

Cannot read Property 'type' of Undefined

         //LOGIN
const [txtUserName] = await page.$x('/html[1]/body[1]/div[2]/div[3]/div[6]/form[1]/div[2]/input[1]');
   await txtUserName.type("[email protected]");
