Hello @Laura
After a while you keep clicking the load more button you will be stopped with captcha, only chance to get the remaining records is by using cloud scraper with proxy which would retry the page multiple times.
Check it out - Web Scraper - Pricing
Meanwhile I made an example tho. Maybe this will help:
