How to add a tab to a Facebook GROUP?

[Amy]

I have seen heaps of help on how to add a custom tab to a Facebook Page but I want to know how to do it on a group. Groups are different to pages.

A few websites have said Settings > Edit Settings but this isn't right. There is no option there to add tabs in the settings for a group. I have tried adding an app. but this doesn't work either. It only allows me to select my Facebook Page as the place to add it to, not the Facebook Group

You Can Not Add Any Tabs To A Facebook Group The Websites that Are Mentioning that Option Are Probably Referring To a Older Group Layout
