Guidance needed for a friend of mine regarding Garda vetting

[Chee]

Hi hope all is well.
A friend of mine is in the process of applying for Irish citizenship by naturalization. She received an email from ISD support today, with a PDF letter attached in the email that has her reference number. In the email itself, there is this "Please ensure that the address we hold is correct before submitting your e-vetting". But she told me that she did not receive any e-vetting invitation.
It has been a while since my application and my application was paper-based so I don't know much about the process for online-based application. Is this quote just for future reference, or does it mean a separate e-vetting invitation should be sent out to her soon?
Appreciate your help. Thank you.
