I believe they already provided "Standard traceroute example", "Flyingroutes example (with protocol breakdown)" and "MTR example (with packet loss and timing statistics)".
But you have to copy those examples from another spot in the post and paste it into the box that is already populated with placeholder information.
And for whatever reason, copy and paste on the page is flakey and required several retries on my iPhone running iOS 26.
I added a Load sample button so you can test it easily
