UI and superuser queries

We have two queries .

Query 1: Kibana Dashboard Users Unable to Export Study Details

Issue:
We have a Kibana setup where superusers (e.g., the elastic user) can successfully download/export dashboard results. However, users with the kibana_dashboard role (e.g., shaan, kanmoh00) are unable to export or download data from a specific dashboard that contains study details.

Question:

Are there any additional permissions or role settings required to allow kibana_dashboard users to export dashboard data? Is there a specific privilege that needs to be added to their role in order to enable this functionality? If exporting is restricted at the role level, is there a best practice to allow certain users to download dashboard data without granting full superuser access?

We would like to avoid providing superuser access just for exporting purposes, so any insights on alternative solutions would be helpful.

Query 2: Hiding Unnecessary Icons on the Kibana Login Page Using Spaces

Issue:
We want to customize the Kibana login page and user interface by hiding specific icons such as APM, Logging, Metrics, and SIEM, as these are not relevant to our end users.

Question:

Is it possible to configure Kibana Spaces to restrict or hide these icons for specific users or roles? Can this be done at the space level, or do we need additional configurations? What would be the recommended approach to achieve a cleaner UI with only relevant features visible?

Any guidance on how to achieve this would be appreciated.
