This exploratory project demonstrates how to set up a discord activity with an arbitrary client.
Building Your First Discord Activity
The Discord Activity Example in the 8thwall Workspace is a good starter template for interacting with the Discord Embedded API from a client. It displays the names and profile pictures of users in the current session.
Follow the instructions in https://www.8thwall.com/docs/studio/native-app-export/html/#Discord to get started.
