Fetch all Facebook Groups user created or admin of

Question

I'm having an issue fetching all groups an authenticated user created or is an admin of.

Here is the endpoint I used:

https://graph.facebook.com/${userId}/groups?access_token=${accessToken}&admin_only=true&fields=administrator,id,name,icon,cover,permissions,privacy

The above endpoint is not returning groups the user created. It is only returning other groups the user is an admin of. This is very weird. I feel that if I created a group I should automatically be an admin to that group. Is that not how it supposed to be? Or is there another endpoint that can help me achieve what I want?

I want to fetch all Facebook groups the user created or is an admin of.

Thanks
