How can EXB app send the portal application "appId" to the portal, for non-public scenes?

[MichaelLev]

For non-public scenes, WAB applications could send the portal application "App Id" to the portal,

via "appId" in the config

But in EXB applications I don't see a possibility for this.

Am I missing something?

I found myself: It's "clientId" in main config file.
EXB Developer system "download" leaves it empty (is it a bug?), and it's needed to be filled manally.
