Instead of having the bot itself post messages from ingame players you can use a discord webhook for this. It would look something like this: https://forum.fivem.net/uploads/default/original/2X/a/a04827d09f137276d066750e0c99a3ef99bc121f.png
Aditionally you can get an image of the player's face from https://www.cravatar.eu to add to the message. (getting the image with the player name doesn't seem to work for most players but it works fine with the uuid)

Already implemented, look for webhook in the configuration explanation

Oh whoops, I didn't notice that for some reason. Thanks for already having my suggestion implemented.
