User Forum/Chat - best tool?

What is the best method/tool to incorporate User Chat within the app, Ideally I would love to link Google Spaces and use that, but since I am unable to, is there a better tool that I can embed within the app or does it make sense to build out the chat database functionality within the app?

building the chat functionality in the app is the best
you will be able to track data f the conversation and see the performance yourself

Why u need that? Build your own self. No need 3 part service at all. With Adalo probably u won’t be able to that (they don’t have real time DB), but if u will search, defo u will find what u want
