Issue with Following Confluence hello world app

I’m currently following the steps provided for part 2 ( but nothing is popping up when I test the app.

Same thing is happening when testing part 3 - I’m not seeing the change pop up.

What are you seeing in the macro? Is it just the “Hello World” text?

Perhaps your tunnel stopped running? Maybe refresh the page?

Yes it’s just the “Hello world” text displaying. The tunnel is still running and I’ve refreshed the page multiple times. It’s still just displaying “Hello world”
