Question: How to add Route Groups?

[ishanvyas22]

I see this project uses nikic/FastRoute, it's not documented on how we can define route groups? Route groups are often used when there are multiple areas(i.e. /admin, /editor, etc.) and developers want to group assign routes to a particular prefix route.

This is already supported by the nikic/FastRoute package as Route Groups, therefore I was wondering on how to achieve this using Framework-X. I tried using addGroup but it doesn't seem to work ATM.
