Hi Kartik,
First, please check [how to ask question in support portal](https://support.gluu.org/docs/user-guide/how-to-ask/), if you just search in support portal with your keywords, you might find relevant community tickets already which will help you to speed up the whole implementation without even asking question to anyone.
As for example, I did a quick 'access control' searching in our support portal and here is what I am getting. Screenshot attached.
Second is, [UMA](https://www.gluu.org/docs/gluu-server/4.2/admin-guide/oxtrust-ui/#uma) which is what you are looking for.
