'How to handle Single<Single<String>> in RX?

I have an api with a method

    fun getList(
        @Path("array") array: String
    ): Single<List<EpisodeRetrofitModel>>

I need an argument to use this method. I get the argument from an RXJava method chain as single : Single <String>, then I try to use it by this way:

single.map{t -> fun getList(t)}

and I get Single<Single<String>> I wonder how i can handle it. What is the right way to use this getList() method?
