Scheduling events with Sesh in Discord is a relatively simple process.
While you could use the slash (/) commands in discord, it's by far more simple to go to the website and schedule from there.
The first thing you'll want to do is make sure to authorize and register via discord so that it can find the servers you have permissions to create events in.
Secondly, find your server, then go ahead and create an event with all the required fields.
