Android 21+:

val publicStorages = ContextCompat.getExternalFilesDirs(this, null).mapNotNull {
    it?.parentFile?.parentFile?.parentFile?.parentFile
}

// paths:
// /storage/emulated/0 
// /storage/12F7-270F

Android 29+:

val volumeNames = MediaStore.getExternalVolumeNames(context).toTypedArray()

val phoneSdCard: String = volumeNames[0]
// external_primary == /storage/emulated/0

val removableMicroSdCard: String = volumeNames[1]
// 12f7-270f == /storage/12F7-270F
