Fiori Launchpad shell plugin to load client information

[#1]

flp-shell.pngHi Community,

Recently I was trying to implement a shell plugin following the below gitHub example to expose the client information on the shell header

https://github.com/SAP-samples/fiori-custom-plugin-abap

Query 1: Unlike the system information appearing on the snapshot attached in the github documentation, I could see the system information not directly available at the FLP shell on load rather I could see when I navigate to particular application in the header dropdown as per my attachment. Could you let me know why is this behavior? and Could you guide me how I can achieve like the one represented in the github snapshot?

Query 2: What is the advantage of loading the system information from the HTTP service as described in the exercise rather than reading these system related information from the cookies directly available at run time?

Thanks in advance for your advise
