[NEW] Canned responses

[reinaldonetof]

Proposed changes

Implemented the feature to Rocket.Chat mobile app to support the ability to select/send Canned Responses while the agent is on a room of Omnichannel.

So, here is implemented the feature to get the canned response from input message in room view [Screenshot 1], besides that the agent can see all the canned responses, filter by text and departments in a new view [Screenshot 2], added a new view to see the canned response in detail [Screenshot 3].

How to test or reproduce

• Be an Omnichannel's agent
• Join an Omnichannel's chat
• In the Room View, write ! in the message input text
• Should appear a list with canned responses
• Or you can click on title header, go to room actions
• Should appear a button with name: Canned Responses
• Click on it, and you should see all the canned responses, that can be filtered by departments and text
• Click on any canned response, should move to detail
• And in both views, if you click the button "USE", you move back to the room view and will appear in message input text the canned response that you selected.
