How to extract a part of a link and then add another part?

Hello Pabbly community

I'm getting stuck at one step in my feed. I'm trying to make a "RSS Feed - Webflow Software - Facebook Page" feed.

I'm attaching what I've done and noting where I'm blocking.

The blocking part is that I have to take a part of a link.
On this example "https://webflow.com/blog/famous-logos"

I have to get the "famous-logo" part to put it after the previous link part.

I do this to retrieve the latest software blog post, have Pabbly check my Google Sheet to see if it's a new post, update it in that Sheet, and then post the link on my Facebook page.

I hope I managed to make myself understood, I come from France and I go through a translator.
If not, tell me in comments and I will answer you directly to give you more details.
