alerting index permission

[hashem-jahangiri]

Hi everybody, when I create a role with index permission that used username variable like logstash-${user_name} and cluster permission for alerting and state, in monitoring section my logstash-myusername index don't show any plot. when I change my role index permission to logstash-myusername all things work correctly. how can I control user permission for accessing to special indexes with one role for alerting?
I use opendistro 1.13.
