Create new app
Click the "Create new app" button. A form will open where you can enter a name for your app. Enter a name, select a cluster location of your choice and click "Create my app". No need to select the tech stack options or select "Create apps for multiple environments".
Go to Channels apps > [select app] and select the tab "App Keys". Here you will find the credentials you will need later when configuring the script.
Write the credentials down and proceed with the next step.
