Can not add “dev=true” to the url

Hi, I've created an app using your CLI.

I copy the first app template.

I start the app via CLI and all works correctly, the only problem is when I try to test it, if I open a ticket with the "?dev=true" attribute I don't see the app.

I see that in the past some user open a thread in your forum, but I don't fund the solution https://community.freshworks.dev/t/can-not-add-dev-true-to-the-url/8086
