What is the importance of the channel manager?

Though I’m aware that the Channel Manager may have certain special authorities or roles in managing group channels on the website, I’m curious to understand more. Why does Sendbird recommend creating a Channel Manager before interacting with group channels? Specifically, what are the potential risks or limitations if we bypass the Channel Manager and allow the existing app user (who logs into the system using a Google account - let’s call them “admin”) to handle group channel interactions directly?*

Additionally, Sendbird has a manual user creation function for users not linked to any Google account (I’ll refer to them as “normal users”). We currently assume these normal users do not have access to the website (where group channel management occurs) and only access the organization’s application. Can I assume that these normal users cannot impact any group channel management functions?
