Delete a parasitic flow in

Hello, I created a new node, but it doesn't appear in the search on the site (it works in Nodered itself):

While the page does exist.

It's a flow that appears, I think I was the one who had to create it at the beginning with the same name as the node,

But the page does not exist.

It is possible that I may have created this page by mistake, so my question is how to delete it?

I'll sort it out when I'm next near my laptop.

Thank you
