I've polished up and consolidated all my Discord webhook analytics prefabs into a single Unity package that works with any Unity game (unless UI or VideoPlayers are blacklisted).
This won't work in SDK3/UDON at all, there should be a different post for that. This version is meant for SDK2 worlds since it's a little cleaner looking and you have more control over the UI color.
Included in this .unitypackage are two prefabs:
Feedback Analytics - Pictured above, type a message and send it to a Discord server
OnEnable Analytics - Sends a message to a Discord server when the GameObject is enabled
