There is a discord server which has a channel with a lot of messages coming in. I am interested only in fraction of them and I want to make an application which will filter new messages using a keyword and notify me when a new message which interests me was posted.
From what I know, you can only use Gateway part of Discord Developer Tools with a bot connected to a server. I doubt the server owner will allow my bot there due to population of the server.
Is there some way I could achieve my goal of using Gateway? If not, is using: https://discord.com/developers/docs/resources/channel#get-channel-messages my only other option?
