Change name of Bot tab in Teams application

Hello! 

I'm constructing a Teams app with a bot service. When I add it to Teams, it shows the bot interaction under a tab named "Activity" 

I would like to change it to display the name "Chat" as in the TeamsConversationBot example: 

Has anyone been able to figure out how to rename the Teams tabs in the app manifest? 

Thanks in advance

Here is the app manifest:
