Messaging SDK | Android | Not able to set "Conversation Tag" and "Conversation fields" in the on-going conversation

I have followed the doc for setting the conversation tag in the zendesk messaging sdk
mentioned here
https://developer.zendesk.com/documentation/zendesk-web-widget-sdks/sdks/android/advanced_integration/#conversation-tags

Adding the code block

//TAGS
List<String> tags = new ArrayList<String>();
tags.add("android-test");
tags.add("messaging-test");
Zendesk.getInstance().getMessaging().setConversationTags(tags);

Zendesk.getInstance().getMessaging().showMessaging(MCBActivity.get());

But i am not able to see the tags getting added if i do reply our chat in the existing conversation.

SDK version is 2.14.1
