Hello, thanks for reaching out. I'm Ace, one of the Independent Advisors. I can understand your concern and please don't worry I am here to help you.
Since your parent's account is a Gmail account, the parental request should still arrive via email, but sometimes Microsoft emails can be filtered into the spam or promotions folder. Your parent should check those folders to see if the request is there. If the email isn’t arriving, they can also check their Microsoft Family Safety dashboard at family.microsoft.com to see if the request appears there. Sometimes, instead of an email, the request is listed in the Microsoft account notifications.
If the request still isn’t showing up, your parent may need to manually approve access by signing into their Microsoft account and adjusting your permissions in Microsoft Family Settings. They can follow the steps outlined in this guide to manage parental consent.

Let me know if you have further questions.
Thanks!
