Web Scrape data from drop down menu

Describe the problem.
Hi everyone, please help me with this one. I need to extract the table data in each of the page from the menu drop down.
I couldn't find a way to get the web scraper to run through all the pages from the drop down menu.
Appreciate your kind help!!!

You can see the menu drop down at:

Sitemap:
{"_id":"vietnam_notification","startUrl":["https://www.customs.gov.vn/Lists/VanBanPhapLuat/Default.aspx"],"selectors":[{"id":"page","type":"SelectorLink","parentSelectors":["_root","page"],"selector":"a#ctl00_PlaceHolderMain_g_cc22d9ee_6412_4276_ad16_5d0d4ef94a61_ctl00_NextPage","multiple":true,"delay":0},{"id":"data","type":"SelectorText","parentSelectors":["_root","page"],"selector":"#ctl00_PlaceHolderMain_g_cc22d9ee_6412_4276_ad16_5d0d4ef94a61_ctl00_Results td","multiple":true,"regex":"","delay":0}]}

Try this, with long enough delays:
