Chrome extension webscraper.io – how does pagination work …

I am trying to scrape tables of a website using the google chrome extension In the tutorial of the extension, it is documented how to scrape a website with different pages, say, “page 1”, “page 2” and “page 3” where each of the pages is directly linked on the main page.
In the example of the website I am trying to scrape, however, there is only a “next” button to access the next site. If I follow the steps in the tutorial and create a link for the “next” page, it will only consider page 1 and 2. Creating a “next” link for each page is not feasible because they are too many. How can I get the webscraper to include all pages? Is there a way to loop through pages using the webscraper extension?
I am aware of this possible duplicate: pagination Chrome web scraper. However, it was not well received and contains no useful answers.

Following the advanced documentation here, the problem is solved by making the “pagination” link a parent of its own. Then, the scraping software will recursively go through all pages and their “next” page. In their words,
To extract items from all of the pagination links including the ones that are not visible at the beginning you need to create another Link selector that selects the pagination links. Figure 2 shows how the link selector should be created in the sitemap. When the scraper opens a category link it will extract items that are available in the page. After that it will find the pagination links and also visit those. If the pagination link selector is made a child to itself it will recursively discover all pagination pages.
