Can't find ElasticSearch on Magento 2

Hi!

I have installed ElasticSearch on my vps, i want to put it on Magento 2.2.5, but when i go in Magento 2 back-end, in Store->Settings->Configuration->Catalog->catalog->Catalog Search i can't find it in the Search Engine.

I have installed the 7.4.2 version of ElasticSearch.

I have followed these tutorials : * https://devdocs.magento.com/guides/v2.3/config-guide/elasticsearch/es-overview.html

If someone had the same problem and solved it, it would be cool.
