How to create/access admin

[utkarshjosh]

Hi, I am learning react as of now, I saw this beautiful project on https://reactjsexample.com/hotel-booking-app-using-the-mern-stack-with-typescript-redux/ I am not able to fully access the site, as I cannot access admin routes, A user object in the database have a isAdmin field, but how is it set? How is an admin user generated, so that it can access all routes?

Can you Please throw some light. Yes I am almost a newbie here.

Edit : For now, I am editing isAdmin field using mongodb
