OpenSearch Security not initialized

Excuse me,When I try to get a message about the OpenSearch cluster, I get an error as follows:
{
“error” : {
“root_cause” : [
{
“type” : “security_exception”,
“reason” : “OpenSearch Security not initialized for cluster:monitor/health”
}
],
“type” : “security_exception”,
“reason” : “OpenSearch Security not initialized for cluster:monitor/health”
},
“status” : 503
}
How can I initialize OpenSearch Security?
