Search for: elasticsearch right to enable

Hi there,
I have a simple question: I am admin for a central cluster mit multiple customers and would like to give the users in their space the rights not only to see the index they have (already by done giving the 'monitor' right as 'cluster privilege' in the respective role), but also to let them see the docs count and the storage size.
My question: What right do I have to choose to make this possible?
Thanks!

I added the index right monitor in the respective role to achieve this.
Could someone from Elastic conform this is the best approach (and not a kind of security breach :wink: ).
Thanks!!
