How do I convert  a `Map&lt;String, List&lt;Items&gt;` into   a `Map&lt;String, List&lt;Product&gt;&gt;` , example:  ```val someMap: Map&lt;String, List&lt;Items&gt;&gt; =  x

 val newMap: Map&lt;String, List&lt;Product&gt;&gt;  = someMap.map { it. }  ??? what to do here?```

Soemthing liek this should work:

```
someMap.mapValues { (k, v) -&gt; 
  v.map { item -&gt; product }
 }
```

<@U1AFFRV1Q> thanks but it did not work: ```   someMap.mapValues { (k, v) -&gt;
                    v.map { item -&gt; Product(it.)}
                }```

Product is expecting arguments in its constructor as its declared like this `data class Product(val brand: String, val type: String)`
