How do you configure things for ngrok exactly?

See https://docs.quarkiverse.io/quarkus-ngrok/dev/index.html until and including stable url.

I also use the next step so I don't have to the domain step in every app but is not required.

So in short:

Add ngrok ext.
Get auth token and set it (.token)
Get stable domain url and set it (.domain)

Run in Quarkus dev.

Apparently smee.io can also push the rawdata now so we could probably enable security now: probot/smee.io@8c33d74

Did some work here but still pending some smee.io changes: #659
