I do not see any way to send files and/or pictures
@jerome-pouiller You can drag and drop and files on the chat area to upload and share. You can also use the markdown image syntax to embed a image by URL !(http://example.com/myimage.jpg).
@jerome-pouiller It's a sandbox room for testing but at a certain point you can create your own private room for testing if it's going to take over the room. Plus I don't have any context on what they are testing exactly. It just makes the room look cryptic and not very inviting for others to test casually.
