Enable X_pack Watcher not showingup Watcher in elasticsearch

[DoDuyen162000]

Hello!! Currently I am using Elasticsearch, kibana, logstash version 7.5.2. I want to enable X-pack Watcher on Elasticsearch. Can someone show me how to turn on Watcher?

This is what I added in file /etc/Elasticsearch/Elasticsearch.yml

Watcher requires at least a Gold subscription.

You can enable a trial license via the API or via Kibana (go to License Management from the screen in your first screenshot).
