RSS integration version

Hello, I want to integrate rss feed but when I try to add url I get error Version is required. I tried multiple feeds and it happens with all of them. For example this is not working: https://www.wpbeginner.com/category/plugins/feed/?format=rss any idea how to fix it?

Are you talking about a custom integration?

What exactly have you tried?

I wanted to use this. Fibery but mentioned link is not working. Since all of the links have same structure for feed I need to solve this one.
