Should we launch a new product or update the previous version?

Hey everyone, We're almost ready to introduce our latest creation on Product Hunt. Initially, we launched a simple Slack add-on called "HAY for Slack" for automated wellbeing surveys. It was a basic version, really the MVP of MVPs. Now, we've developed a web app that's a step up, designed for tech leaders and integrated with GitHub, but it still connects with our original "HAY for Slack" add-on. It's part of the same ecosystem but a completely new application. As we prepare for the launch, we're debating whether to present this as an entirely new product or an update to our previous ones. How do you think we should approach our Product Hunt launch? Thanks for your support and looking forward to hearing your thoughts!
