How to scroll to the bottom of scrapy and then return to response after all the contents of the page have been loaded

the website I am crawling now displays only 20 pieces of data. Only when the mouse scrolls to the bottom can it display another 20 pieces, and then scroll to the bottom to continue to display all 60 pieces of data

.

how can I achieve this effect with selenium in scrapy? Scroll to the bottom until all 60 pieces of data have been loaded before returning to response
