gettingGuildMembers.py

# Keep in mind that there's no actual api endpoint for users to get guild members.
# So, to get guild members, we have to request for and read the member list.
# This is all handled with the bot.gateway.fetchMembers(...) function :) . This function can either be run while the gateway is connected or before the gateway connects.
# Note, you'll need to connect to the gateway to get the member list.
# An example usage is below. The Guild and Channel ids used are from the fortnite server (652k members, around 150k of those are actually fetchable).
# The number of fetchable members changes from time to time.
