Submitted application without use of IMM5475 (help please)

[Ohcanada!!]

Hey everyone,
Asking on behalf of my parents
They have submitted an application but did not attach an IMM5475, now am I allowed to access their tracker without this form?.
What does this form mean exactly, does it govern communication with IRCC to check status application but not the tracker?

thank you appreciate your assistance

To add this is the form to release personal information to a non representative
