[client-side] Chat not included within export presentation

[1Luc1]

Client side version works good for me, besides the chat isn't rendered into the final export video. The download_client.rb script downloads the slides_new.xml file without any problem and seems valid to me.

The export_presentation.rb scripts generates the chats folder with the chat.svg file in it. The chat.svg file looks good to me. The final export video is empty (white) on the left side panel.

Some output from the export_presentation.rb script:
