web scraping web crawling a pdf document with url that changes on the website with python

I am new to web scraping and I want to automatically download from a list of websites a pdf document. This document is updated on a monthly basis and the url changes on the website. e.g https://fundcentres.lgim.com/fund-centre/OEIC/Sterling-Liquidity-Fund I want to download the 'factsheet' pdf document from the above website. I think the ideal way would be the code to 'press the factsheet and saves it to a location on the drive, can someone help me with this please?

Appreciate your help!!!
