Not able to extract Price of product in list page

I try to extract the price of each product from list page.
I got : Tổng giá: 8.980.394 ₫
I want to get (8.980.394 ₫) or (8.980.394)
I try Regex to get that price, however, I get no success

Url:

Sitemap:
{"_id":"a-1-5-samsung","startUrl":["https://www.samsung.com/vn/refrigerators/all-refrigerators/"],"selectors":[{"id":"page","parentSelectors":["_root","page"],"paginationType":"clickMore","selector":"a.cta--icon","type":"SelectorPagination"},{"id":"wrap","parentSelectors":["page"],"type":"SelectorElement","selector":"div.pd03-product-finder__content-item","multiple":true},{"id":"Title","parentSelectors":["wrap"],"type":"SelectorText","selector":"p.pd03-product-card__product-name-text","multiple":false,"regex":""},{"id":"Price","parentSelectors":["wrap"],"type":"SelectorText","selector":"p.pd03-product-card__price-main","multiple":false,"regex":"(?<=: )(.+?)(?=₫)"},{"id":"Image","parentSelectors":["wrap"],"type":"SelectorImage","selector":"img","multiple":false},{"id":"url","parentSelectors":["wrap"],"type":"SelectorLink","selector":"a.pd03-product-card__product-name-link","multiple":false}]}

I just found out with regex: ([^\s]+)\s+₫
