## Usage

### Lua

```lua
SetMaskOverlay(maskName)

-- always available, by hash
Citizen.InvokeNative(0x21F00E08CBB5F37B, maskName)
```

### JavaScript

```js
SetMaskOverlay(maskName);

// by hash
Citizen.invokeNative('0x21F00E08CBB5F37B', maskName);
```

### C#

```csharp
Function.Call((Hash)0x21F00E08CBB5F37B, maskName);
```

- The name is a community guess and may change. If the named call is missing in your client build, use `InvokeNative` with the hash — it always works.
