Elasticsearch + mongo how to link?

Question

MongoDB

I've been trying to link mongo with elasticsearch all day. I read a bunch of guides, but they are all either outdated. Or not complete. And so can you send me a link on how to deploy Elasticsearch + mongo. And use node js to communicate with them. I will be grateful for any help.
PS below is the most normal guide I found, but it was written 7 years ago :(

sudo /usr/local/elasticsearch/bin/plugin -install elasticsearch/elasticsearch-mapper-attachments
sudo /usr/local/elasticsearch/bin/plugin -install richardwilly98/elasticsearch-river- mongodb
sudo /usr/local/elasticsearch/bin/plugin -install mobz/elasticsearch-head
for example the first one
