Spark Scala: Extract values from a struct

Question

I have different dataframes with different numbers of languages here is one example:

 |-- Data: struct (nullable = true) 
 |    |-- languages: struct (nullable = true) 
 |    |    |-- swe: string (nullable = true) 
 |    |    |-- fin: string (nullable = true)
 |    |    |-- den: string (nullable = true)

is it possible to extract the languages swe, fin and den?

My plan is then using withColumn with coalesce with the extracted values.
