How to upload sign in sing out scripts in new Roku Dashboard?

Hi, during publishing process the Channel Behavior Analysis fails for my application. Thisi is because of the authentication flow in the beginning. I wanted to upload the sign in/sign out scripts, but I can find an option to do that in new dashboard UI.

Here is the link to the documentation for the old UI:

https://developer.roku.com/en-gb/docs/developer-program/certification/cert-tests/authenticated-cert-testing.md#writing-automated-sign-in-and-sign-out-scripts

Does someone know how to achieve that in the new dashboard
