Drag&Drop of Attachement to an Rainbow User during a PSTN Call

Dear Rainbow team,

could you please consider a functionality to share during a call:

Today you can click on the picture in the call control popup and came to the users chat window which is not clear from th eview of the user if you don't know it. Maybe here should be an additional icon or symbol.

And as mentioned in the screenshot it would be great to drag a document.

Thanks

BR
