Test Scenarios

Create/update/delete scheduled event + add/remove user from it via discord client or this library.
Make sure you have enabled GUILD_SCHEDULED_EVENTS intent.

Create listener for each event

@interactions.listen()
async def create(event: events.GuildScheduledEventCreate):
    print(event.scheduled_event)


@interactions.listen()
async def update(event: events.GuildScheduledEventUpdate):
    print(event.before)
    print(event.after)


@interactions.listen()
async def delete(event: events.GuildScheduledEventDelete):
    print(event.scheduled_event)


@interactions.listen()
async def user_add(event: events.GuildScheduledEventUserAdd):
    print(event.scheduled_event)
    print(event.user)


@interactions.listen()
async def user_remove(event: events.GuildScheduledEventUserRemove):
    print(event.scheduled_event)
    print(event.user)
