Chatbot UI in Angular

I need an elegant Angular chatbot UI which could make a REST POST API call. The text which user types-in need to be submitted to an end-point and response to be shown on the chatbot UI. I don't expect to build it from scratch since there are so many Angular UI's available on internet. Just grab one which should have following features : 1. Use can hit [Enter] to submit. (that is, no need to click on 'send' button every time) 2. User should not need to scroll down every time as the chat goes on. The UI framework should be free. I expect the winning bidder to show the sample UI (either in terms of screen-shots or www link) before customising it (,if any) for my requirement. I would need your help in deploying it to Azure App service (as I understand, all I've to do is to upload the contents of /dist/directory to /wwwroot/. So, the overall scope is : 1. Find a UI 2. Customise it w.r.t REST post end points (I'll provide the end points) 3. Deploy to Azure. 4. Basic documentation so as to install the app in my local machine. I expect to select the bid today or tomorrow so that the work can be complete by Friday EOD. This is a simple project. An experienced developer should not take more than 3 hours to compIete including deployment. Either me or one of my team mate in India will be available for contacts. My budget is not more than US $ 30. All the bids above US $ 30 will be straight away ignored. Winning bidder might get more work on this and other project. Happy bidding.
