One or more of your connections are currently using Autho development keys and should not be used in production

I currently followed
https://manage.auth0.com/dashboard/us/dev-ge2yk10tj71ab5mk/applications/SpecvK1WGDwi5VQq0DqWfox8IAicrWl0/quickstart
to integrate this to our angular application

when auth popup login screen show, at right top of corner there is a red rectangle,
and show above error message.

how to get rid of that error message?
how to get production key?

Hey there!

In order to handle that most effectively can I ask you to raise it as a GitHub issue in the quickstart repo so we can discuss it directly with the repo maintainers? Here it is:

Once you have a link to the issue make sure to share it here so we can ping them. Thank you!
