Get the previous adjacent edge to the edge given.



```js
getPreviousAdjacentEdge(tag: String, extrude_group: ExtrudeGroup) -> Uuid
```

### Examples

```js
const exampleSketch = startSketchOn('XZ')
  |> startProfileAt([0, 0], %)
  |> line([10, 0], %)
  |> angledLine({ angle: 60, length: 10 }, %)
  |> angledLine({ angle: 120, length: 10 }, %)
  |> line([-10, 0], %)
  |> angledLine({ angle: 240, length: 10 }, %, 'referenceEdge')
  |> close(%)

const example = extrude(5, exampleSketch)
  |> fillet({
       radius: 3,
       tags: [
         getPreviousAdjacentEdge("referenceEdge", %)
       ]
     }, %)
```
