Currently you are integrated with Slack. Google Hangout Chat is a great alternative to Slack and it is very feature rich ( bots and integrations are increasing). It already has integrations with Giphy,Trello to name a few. Also being google it has a very large user base and increasing. A integration with them will help your user base that are on google and also introduce Google Hangout Chat users to Notejoy.
