While using coroutines how do we map the domain model to a network entity?

According to the MVVM Architecture, the use of a data mapper class is mandatory as it maps the entity to the domain which can be used in the presentation layer. While using coroutines, do we explicitly need to create a Mapper Class. For example this is the DataMapper class :

class PermissionDataMapper @Inject constructor() {

fun mapEntityToDomain(permissionEntity: PermissionEntity): PermissionDomain {
    return PermissionDomain(
        permissionName = permissionEntity.roleDesc,
        permissionId = permissionEntity.roleId
    )
}

fun mapEntityListToDomainList(permissionEntityList: List<PermissionEntity?>): List<PermissionDomain> {
    return permissionEntityList.map { permissionEntity ->
        mapEntityToDomain(permissionEntity!!)
    }
}}

Which is further used inside a DataRepositoryClass which maps the entity list to a domain list :

 override fun getSharePermissions(): Observable<List<PermissionDomain>> {
    return userDataSourceFactory.retrieveRemoteDataSource().getSharePermissions().map {
        return@map permissonsDataMapper.mapEntityListToDomainList(it)
    }
}

Do we need to follow this same pattern if we use coroutines? Or does the mapping of domain to entity or entity to domain happens in the background automatically ?
