Discord currently does not support specifying the type of the activity. This field is only used for event handlers and will be ignored when setting an activity through the Game SDK.

See JavaDoc for Acitivity#setType(ActivityType): https://github.com/JnCrMx/discord-game-sdk4j/blob/9cfd70a72c4393c292ea5b037426d5f24c6e434f/src/main/java/de/jcm/discordgamesdk/activity/Activity.java#L96

And from the SDK documentation (https://discord.com/developers/docs/game-sdk/activities#data-models-activitytype-enum):

ActivityType is strictly for the purpose of handling events that you receive from Discord; though the SDK/our API will not reject a payload with an ActivityType sent, it will be discarded and will not change anything in the client.
