How to expose global variable via setting config ?

[acctesttemp]

Love this Node-Red style in Vscode. It can be configured to the same configuration and using same "flow.json" with outside, but how can I get global variable outside ( os, path ... also "electron" ) to this instance Node-Red via setting config as "readme" doing ?

Many thanks for any hint to expose global variable in Vscode, I think it's need for us to make seamless between in and outside instance Node-Red. As I know Vscode using electron in the base, please correct me if I miss sth :).
