Hi @NicholasT1,
In addition to the responses provided by @dbrace and @Chris_Hofer, I wanted to add one more piece of info... Instructure, the company behind Canvas, does offer official support via chat if your school/institution pays for that service. My institution does pay for it, and the agents on chat usually answer most basic questions within a few minutes.
The community here is available to everyone at no cost, but the responses are usually provided by other users from around the world who are just helping others in their free time. Sometimes questions here will get answered within a few minutes if someone is looking at the right moment and knows the answer, but other questions may not get answered for days if they are very complex, specific to a certain school/institution, or need to be answered officially by support (which someone will usually let the person who posted the question know at some point).
All this to say that even if the community here did have an "official" discord, it probably wouldn't get you answers any faster (and could end up making things worse by fragmenting the user base). As @dbrace suggested, maybe your school/institution would be willing to create their own discord space and have staff monitor it and provide answers, as that seems the most feasible route forward for this idea in my head right now.
