You'll need to give more details on what you're looking for. For example, are you looking to get all the "news feeds" from this page (
https://manama.thaiembassy.org/en/content-category/) ? You'll need to get the data somehow. Maybe scrape it and put it into baserow and create your own API endpoint (lots of options for this).
Or are you looking to just move that site into Webstudio entirely? If so, that's going to be a bunch of copy/paste of the text and you'll need to design each page.
