Is it possible to get eBay item description with requests and BeautifulSoup?

I am trying to collect data from shoes on eBay. For every item I want to collect all data including the custom description to build up a database. I have collected all aspects such as price, shipping title etc. with requests and BS4. Unfortunately, the only thing missing is the custom item description.

This seems to be an event html, which in a browser is loaded automatically, but not with requests and BS4. I would prefer to do it with requests and BS4, as the script is almost ready, and scraping through for example Selenium is much slower. The example I am working on is as follows:

from bs4 import BeautifulSoup as soup
import requests

source=requests.get("https://www.ebay.com/itm/SIGNED-2000-NIKE-AIR-JORDAN-1-HIGH-BANNED-1985-ROOKIE-RETRO-SHOES-AUTOGRAPH-UDA/392861887827?hash=item5b7864ad53:g:njcAAOSw9rpfALFX")
Nike_shoe = soup(source.text, "lxml")

The description part I am trying to filter contains, among other lines, the following excerpt:

This can be found a bit lower on the eBay page. This description is part of the following HTML structure:

When I scan through the Nike_shoe soup, this text is not present. I have tried to parse the source.text as lxml, html.parser, html5lib and xml.

I have also tried to use Requests-HTML package which should have full JavaScript support:

from requests_html import HTMLSession
session = HTMLSession()
source = session.get('https://www.ebay.com/itm/SIGNED-2000-NIKE-AIR-JORDAN-1-HIGH-BANNED-1985-ROOKIE-RETRO-SHOES-AUTOGRAPH-UDA/392861887827?hash=item5b7864ad53:g:njcAAOSw9rpfALFX')
Nike_shoe=soup(source.text, "html5lib")

But unfortunately, I was still not able to retrieve this data. Also I am not familiar with this package, so perhaps I am doing something wrong.

Both answers below (@Andrej Kesely & @p1xel) give correct results. p1xel his answer can be implemented as follows:

source=requests.get("https://www.ebay.com/itm/SIGNED-2000-NIKE-AIR-JORDAN-1-HIGH-BANNED-1985-ROOKIE-RETRO-SHOES-AUTOGRAPH-UDA/392861887827?hash=item5b7864ad53:g:njcAAOSw9rpfALFX")
Nike_shoe = soup(source.text, "lxml")
iframe=requests.get(Nike_shoe.find(id="desc_ifr")["src"])
Custom_description = soup(iframe.text, "html5lib")
print(Custom_description.find("td").text

As p1xel his answer is completed through the requests format on the same page, this will be chosen as the accepted solution, but both solutions are fine.
