I can't storing data in blob storage in azure

(continuing from here)

Hello my friends,
This is my first application sending azure information. The problem I have is that I can not store messages in the blob storage that I created.
I took the steps that photon recommends in the documentation to connect with azure and perform every step that indicates azure to save the messages in the Blob Storage but when I review the information it appears empty.
I apologize for this, but I can not find a solution to this problem.
thank you for your patience.
This is a configuration about particle and azure:


Could you please make public the link to the documentation?
