How to install watcher on elasticsearch 7.1.1

Guys i need help here, i have elasticseach,kibana and logstash setup
And i need to setup my alerting and reporting plugin, so i came across watcher but i'm getting this error when installing

Watcher is already included in the default distribution, so you do not need to install anything, just upload a commercial or trial license to enable it.

Thanks. just read it in the documentation.
