How to pass elastic_username and elastic_password to elastic.client.php Bagisto?

Kamdjou

@devansh-webkul
Please I am see from this link https://devdocs.bagisto.com/1.x/advanced/indexing-products-to-elasticsearch.html#setting-up-environment that I can setup Elasticsearch for Bagisto.
But, I am facing the security issue. My elasticsearch engine need authentication to connect.
Please how do I passed the elastic_username and elastic_password in the elastic.client.php file?

Also, I want to know if this will be automatically make the search bar autocomplete (real-time as you are typing).

I really need this feature.

Many thanks in advance
