[vhristov5555]

1. Create new javascript app
2. Add nativescript-nativechat tns plugin add @progress-nativechat/nativescript-nativechat
3. Add demo code from https://www.npmjs.com/package/@progress-nativechat/nativescript-nativechat:

<Page loaded="pageLoaded" xmlns:nativechat="@progress-nativechat/nativescript-nativechat">
    <nativechat:NativeChat config="{{ nativeChatConfig }}"/>
</Page>
exports.pageLoaded = function (args) {
    var page = args.object;
    page.bindingContext = {
        nativeChatConfig: {
            botId: '5acddd9715e7187c15f3fc28',
            channelId: 'f91f065c-4079-4fa9-8860-b893e2b81696',
            channelToken: '0570f9a5-6c0e-4b77-b06d-20ce6d5c56d8',
            user: {
                name: 'John Smith'
            },
            session: {
                clear: true,
                userMessage: 'Book a doctor',
                context: {
                    company: 'Progress Software',
                    phone: '555 555 5555'
                }
            }
        }
    }
};

4. Run the app on the emulator tns run android
   Actual: The demo app will not work:
