This macro generates a list of recent items in a RSS feed chosen from a user-editable list of feeds, then allows the user to choose a URL from the list to open in a web browser. Because the macro leverages Shortcuts to generate the list of feed items, which are then imported back into the KM macro, you will need to reproduce exactly, or download and install, the companion shortcut, "Get RSS Feed", to make this work.
I've tested this on the three feeds in the macro as uploaded. Some feed URLs cause the Shortcut to time out or otherwise throw an error. I'm not sure why.

GET RSS FEED; SELECT URL TO VIEW.kmmacros (10.1 KB)
I strongly recommend downloading the companion shortcut because it took me hours of tinkering with it, including figuring out exactly how to construct the feed item list textually so that the KM macro would handle it correctly. To wit: the "Text" action MUST sandwich "Name:URLs" between two linefeeds, above and below it. Thus, I say download as opposed to attempt to reproduce manually.
Cheers!
Here is the shortcut:
