Scanamo Paginated Query Issues

Question

Need example of a method to create paginated query on dynamoDb using scala's, Scanamo library

I am trying to create to create a method which performs paginated queries on dynamodb table using a query on secondary index. I tried using scanamo but this doesn't works.... Additionally I am not sure how queryPaginatedM() works, since there is not much documentation available for scala newbies.

https://github.com/scanamo/scanamo/blob/master/scanamo/src/main/scala/org/scanamo/SecondaryIndex.scala

    protected def querySecondaryIndexPaginated[T, U](
          query: Query[T],
          table: Table[U],
          indexName: String,
          pageSize: Int,
          lastEvaluatedKeyOpt: Option[Map[String, AttributeValue]]
      )(implicit format: DynamoFormat[T]): Future[MyDynamoResult[U]] = {
        val queryRequest: ScanamoOps[List[Either[DynamoReadError, U]]] = lastEvaluatedKeyOpt match {
          case Some(lastEvaluatedKey) => table.index(indexName).limit(pageSize).from(UniqueKey(lastEvaluatedKey)).query(query = query)
          case None                   => table.index(indexName).limit(pageSize).query(query = query)
        }
        scanamo
          .execFuture(queryRequest)
          .map....
