**Examples**

```csharp
// Make sure you have attached the listeners you need before connecting the client, or you might miss some events.
client.Connect()
```

### Disconnect

Disconnect the client from RELAY.

**Returns**

`void`

**Examples**

```csharp
client.Disconnect()
```

## Events

All available events you can attach a listener on.
