To get layers of a web-map portal item, load the portal item to the map, and get the list of operational layers using:

map.operationalLayers

val portal = Portal("Your-Portal-URL")
val portalItem = PortalItem(portal, "Portal-Item-ID")
map = ArcGISMap(portalItem)
map.addDoneLoadingListener {
    Log.i("TAG","Number of layers: ${map.operationalLayers.size} ")
    val firstLayer = map.operationalLayers[0]
}
