Create presence for consumer:

`self.presence = await ChannelPresence.create_from_consumer(self, groups=(PUBLICATIONS_SCHEDULE_GROUP,))`

Example of create:

`class Consumer(AsyncJsonWebsocketConsumer):
async def connect(self):
self.presence = await ChannelPresence.create_from_consumer(self, groups=(CONSUMER_GROUP,))`

Groups are needed to send join and leave messages.

`await self.presence.join()`

Leave user:

Get users:

`await self.presence.get_users(GROUP)`

`{
'user': SimpleLazyObject of User,
'is_active': True or False
'present_at': Datetime
}`

To set the activity expired time use `EXPIRED_USER_ACTIVITY` in django settings.
