How to edit the amount of my blog posts displayed in my front page?

Hi there! I have this Scandinavian interior design & home renovation blog, Kotimussukka: https://www.kotimussukka.com. Things are now up and running but I have a problem: how can I edit the amount of posts that my front page shows? I use Wix Website Editor and there I have this "Magazine" layout selected but damned haven't figured out a way how to limit the number of posts visible in my front page. Now all of my 15 posts appear in the front page and I would rather have the amount go down to six. The rest of the posts would be seen when clicked "next", "more", or something like that. Attached a picture showcasing my site and its layout.

Any tips regarding this topic would be highly appreciated! :)

Best,

Ilona
