Give User access to execute particular query

Elastic Stack Kibana
1

Index Name : sampleindex@timestamp
Everyday new index is being created with current date

I made one user in kibana and assigned a particular role to the user:
I already added sampleindex* with privilages:

 monitor, index, read, view_index_metadata

to the role assigned to my user but still my user is not able to execute:

GET /_cat/indices/sampleindex*

my question is, how to give my user access to execute this particular query.

Have you set cluster privileges too?

cat indices API Document says user need also monitor or manage cluster priviledge and monitor or manage index priviledge.

Thanks @Tomo_M, Giving "monitor" cluster privilage to the user worked...
