Changelog Entry
Fixed
Description
When the user press ENTER or click on the "Send" button, while leaving the message empty or offline, Web Chat will not send the message.
However, we should also alert the user about their mistakes via screen reader.
This PR adds an alert when sending empty message or offline.
Design
We are adding an assertive live region inside the send box. It will hold the error message.
The error message will be triggered by three UIs: single line text box, multiline text area, and send button.
Since 3 different UIs need to show the error message, we are adding a new
<SendBoxComposer>to handle the coordination. The new<SendBoxComposer>should also handle interactions related to the send box.However, due to time constraints, we cannot fully complete the
<SendBoxComposer>. We will complete it when we are working on the customizable send box work (#1839).Specific Changes
