Please check the screenshots from the previous page. I posted my settings and the input.
I did it different than you. Specifically, I didn't enter the username/password in the Endpoint Generator. For protocol I used endpoint

ort.
In the output you need to replace "username" with your username (the one they sent you per email, usually starts with "s"). Then for username you enter your email. For password you enter the one they sent you per email or the one that you have set.
Two accounts had the same name (My first and last name) but a different username. For both of them, Meta Verified was available. The third account was the personal account of my friend.
Depending on your operating system you can also change it in the settings.
Important: Your pictures have metadata (location, time, etc.) in them. If you took a picture in your hometown, and upload it, Instagram will know the real location even tho you are tagging a different one. A way to get rid of these metadata is to make a screenshot of your original image.
Also, Instagram will get your location from the 4G proxy. For them, it doesn't really matter whether you show your location. However, I think it can be beneficial and help them to understand you are in the US/AUS/UK.
