@amritkv, is it not better to restrict pages by user groups?
This sound really flaky

Hey @heliocastro, Yes, I do agree on this. Actually, I just extended the existing implementation that is to check for all /admin/* and not only /admin for the time being.
May be after our first release, we'll remove the regex-based matching completely.
What do you think ?

@amritkv We need sit down on this one. The regex match is far from a good approach. Did you verified what is the solution using next-auth capabilities ?
We do have user authenticated, we can pass group on auth and some necessary info.
