How do I change my App Store review name?

I used to be able to change my App Store name. Now I can’t even find out what it is currently. I don’t have a computer of my own. I live with my parents who freak out at the very suggestion that I need to use their computer for anything. They’ve only let me once (when my phone crashed and I HAD to have a computer because the tech support guy was on the phone saying I would have to) and they were NOT happy about it. Mainly my mom… & she’s the one who uses it daily for her work. I would never be able to use it to change a username if she wouldn’t let me use it when my account data was ready for download and it refused to let me download on my phone.

And here's what the community specialist says:

"While you are not able to change the nickname from your iOS device, you can use a computer to do so.

If you're using a Mac, open the macOS App Store and click on your name at the bottom of the sidebar on the left. If prompted, sign into your Apple ID. Then, click "View Information" from the upper right of the account page. Once the next page loads, scroll down to the "Manage" section. Here you will see your nickname and have the option to edit it. Changing the nickname here will change how the nickname appears when leaving comments/reviews on apps.

If you are using a Windows computer, you can change your nickname by clicking Account > View My Account. If prompted, sign in with your Apple ID. Scroll to the "Settings" section and click the edit button next to your nickname: Set up and manage an iTunes Store account on PC - Apple Support."
