Is anyone can describe a comments to this interface?  
interface IOmnichannelSourceApp {  
type: ‘app’;  
id: string;  
// A human readable alias that goes with the ID, for post analytical purposes  
alias?: string;  
// A label to be shown in the room info  
label?: string;  
sidebarIcon?: string;  
defaultIcon?: string;  
}

Especially for "id’ filed ( is it id of app or any uuid) and “sidebarIcon” with “defaultIcon” (what need to set? base64, base64 with data uri, link to file? Is it possible to use svg or png)?

I found solution, need to create public endpoint with the name ‘get-sidebar-icon’.  
sidebarIcon and defaultIcon are names of svg icon files that where get-sidebar-icon will return.
