How to Set global Variable in Katalon Studio Version 7?

Hello Guys,
I am trying to Set Global Variable into Katalon Studio Version 7, but not able to do that.

To Set global Variable, first need to create variable into Profile (Default) or whatever profile you have selected.

and while defining variable into script just need to put GlobalVariable. before variable

eg. GlobalVariable.RequestNO

for reference i have attached video link.
