RSS Feed onto SS site?

Looking for a solution on how to get an external rss feed onto a SS site? Im making a local pharmacy a new website and they want the national pharmaceutical news rss feed on their site (rss feed i want on my site is: https://www.apteekki.fi/terveydeksi/uutiset.rss)

I contacted support and they told me that they don't have a solution built in. So I have to use a 3rd party widget. Any suggestions? Customer of course would like a free solution for this.. But let me know what rss readers have you used on squarespace sites.
