Storefront Detect Market of B2B customer

Hi, I am looking for a way to detect what actual market of a B2B customer when they visit my store. If I get market attribute from liquid it actually return a DTC customer.
I have tried to use localization.market and customer.current_location.shipping_address.country.market but they return same result that not what I expected. I want to detect actual market of that B2B customer which I setup in Market setting of store.
Thank you.
