Does anyone know if there is a written or video break down of the standard group chat flow (with bubbles or threads...doesn't matter) that details the structure and workflow of how it operates? For example, the role and sequence of the page state variables, firestore fields, and params in the pages and components. It's a bit of a tangle, and I'm trying to get it all straight in my head (including the User_A, User_B fields...which I get in general, but gets a bit muddy when poking through the visual builder looking for how and why they are set and used between components and pages), because I'm doing some surgery on the flow to enable the addition of a different chat contributor that isn't a user in the Users collection. Has anyone found a good description of the Flow? (The documentation is very high-level.)
