Credentials.yml question

Hi, What does this commented out line means in credentials.yml ? How and when to use ?

#rasa:
# url: "http://localhost:5002/api"

You need that if you are using Rasa X. There are the credentials for the Rasa X “channel”, i.e. talk to your bot and share your bot.

Ah, I see, thanks ! Can this be modified to rasa-X for better understanding pls ?

#rasa-X:
# url: "http://localhost:5002/api"

Not sure if that is more understandable. Would instead add a comment to explain what it is for.

Thanks
