Hey @vorleakyek
Thanks for your comment and testing out the PR!
Sure
Let me guide you through the whole process

Step 1. Building the API address
The new api has been added in users.router.js, and if you look at the comment at the top
It says that the base url is /api/users

That means that to hit our specific api we will have to call
"server-url"/api/users/admins
here "server-url" is the name of our node server
which when building locally is usually http://localhost:3000

So the end point for the API would become
http://localhost:3000/api/users/admins

Step 2: Getting authenticated
Now that our API endpoint is ready
Please make sure you have the ''x-customrequired-header" set in your request
It is a security header generated on signin to authenticate the admin for every request

To get the value of this header

1. login to your admin account in VRMS
2. Open the network tab in chrome/other browser of your choice
3. Click on any tab - users/projects etc.
4. when clicking on those tabs you will see that there is a corresponding request in the network tab
   
5. On this request, get the "x-customrequired-header" value in the headers
   

Copy this value and add to the headers in the request

Your Request would become
curl --location 'http://localhost:3000/api/users/admins'
--header 'x-customrequired-header: custom-header-here'

Please not that you would need to replace custom-header-here with your own header you find from the other request
Please feel free to reach out if you have any more questions

@ntrehan, thanks for the details testing information. It's very helpful!
The code looks good, and it seems like the return data have one "superadmin" and the rest are "admin" for the accessLevel.
Thanks for working on it.
