Unable to find what? The localization dashboard, or those settings? How much of your localization pipeline have you actually set-up? Do you have anything localized at all right now?
The localization dashboard can be found under “Window” → “Localization Dashboard”.
“Export Script” will export a dialogue sheet, “Import Script” will import a previously exported one back (in the case that copy-edits were made during recording), and “Import Dialogue” will import WAV files from the “Raw Audio Path” set in the settings. For these options to work, you need to have an asset gather that includes your dialogue waves, and you need to have translations for the spoken text of the dialogue wave contexts.
Yes, manual means you just create and set-up the appropriate localized assets by hand.
