Xpathonurl - Pulling Live Retail Prices

I am having a hard time pulling the retail price for this particular item. This is the link to the product:

https://www.amazon.com/dp/B07PK1CTF6?th=1

This is what I am currently trying to use to pull the retail price:

=Xpathonurl(https://www.amazon.com/dp/B07PK1CTF6?th=1, //*[@id="corePrice_desktop"]/div/table/tbody/tr[2]/td[2]/span[1]/span[2]
, "Retail Price")

It just returns blank. Please help,

This XPath works for me:
=XPathOnUrl("https://www.amazon.com/dp/B07PK1CTF6?th=1","//div[@data-feature-name='corePrice']")
