Filled wrong information on Visitor visa Application

[ITSAVY]

Hi, I'm applying Standard Visitor Visa(6 months) for my Mother to visit UK. I learnt that I have submitted wrong place on "Place of birth" section. I have done the payment charges for the 6 months visa and I'm yet to book Boimetric appointment. Can anyone advice how to rectify the error.

Write a cover note or letter addressing the error and stating the correct date of birth. Upload this before biometrics appointment.
Are the passport and other documents showing correct place of birth?

Thanks AmaZonianX for your reply. Yes, The passport is showing correct birth place. As suggested, will include a correction note in the cover letter. Thanks again!
