How Can I scrape the data for all the pages? Kindly help in this regard.

{id:"sitemap code"}

For pagination, you should refer to the
Web Scraper pagination tutorial

For this site, you can use either the first type or the second type, "use link selector to navigate the pagination pages" at around 1:48. If you choose the first type, you'll need to do some math and figure out the increment and ranges, as described here, under "Use range url with increment". The increment seems to be 12.
