Adding passport details after 189 visa lodge

Hey all, we just lodged 189 visa last week. At that time we did not have passport for our newborn and hence submitted without it. We just got the passport but not able to add the passport details via the immi account. Looks like I may have to fill up an online form asking them to update. Anyone been in this situation before? If I update it via the online form, do they update it in our immi account?

Yes, they will be able to update if you send them the information.
