Go Rod If Button

Trying to determine if a particular button exists on a page, if the button doesn't exist this code seems to freeze instead of continuing. Any ideas what options there might be to determine if the button exists or not on a page without the code stopping? :)

package main

import (
    "log"

    "github.com/go-rod/rod"
)

func main() {

    urlSlice := []string{
        "https://www.amd.com/en/direct-buy/5450881700/us",
        "https://www.amd.com/en/direct-buy/5458373400/us",
    }

    for {

        for _, url := range urlSlice {

            page := rod.New().MustConnect().MustPage(url)

            btn := page.MustElement("#product-details-info > div.container > div > div > div.product-page-description.col-flex-lg-5.col-flex-sm-12 > button")

            if btn.MustText() == " ADD TO CART" {

                log.Printf(
                    "%s \t %s",
                    page.MustInfo().Title,
                    btn.MustText(),
                )

            }

        }
    }
}
