```
_required_
A string that uniquely identifies the layer in the style to which it is added.

string
```
Inserts a layer above aboveLayerID.
### belowLayerID
```tsx
string
```
Inserts a layer below belowLayerID
### layerIndex
```tsx
number
```

### filter
```tsx
FilterExpression
```

### minZoomLevel
```tsx
number
```
_required_
The minimum zoom level at which the layer gets parsed and appears.
