Step 1: The Chat window allows you to send text messages, as well as view the transcript of the session. (Fig. 7, Below) (8)
Step 2: To send chat messages, please enter the text in the designated field. (Fig. 12, Below) (1)
Step 3: Upon clicking on “Send” your message will be sent and will then appear in the chat history visible to all users. (2)
Step 4: You also have the possibility to upload image files to the chat (3) and share them with other users or edit them together.
