How create a role for creating index and ingest on it

Hi;
I want to create a role with these privileges in "Index privileges" section:
[ create_index , create, create_doc, index]

There is a box to select which index the role can have access:

I have some agents with this role which create and add docs to new_index.
I should choose * for index section so agent can create and ingest. in this situation the agent can access to all Indices. But i want agent can create an index and just access to that index, not other indices.

How can I do it?
