Does Elastic-sink connector work with elastic cloud?

Hi everyone!
I tried a simple example with elastic-sink connector in Confluent Platform and I observed that if I connect my elastic-sink connector with elasticsearch in local(http://192.168.x.x:9200) it works well, but if I use my elasticsearch cloud the conenctor fails. So as far as I understood the elastic-sink connector does not work with elastic cloud, right? The example is the follow: https://docs.confluent.io/kafka-connect-elasticsearch/current/overview.html

Jessica,

It usually works, but it would help if you could share what is the error you’re getting while connecting with Elastic Cloud.

I followed the example and the connector is correctly created but when I searched for the index into elastic with curl -XGET ‘http://localhost:9200/test-elasticsearch-sink/_search?pretty’, I didn’t find anything and the connector in confluent platform switched to failed. I tried to see the error and I found this:

Did you created a role with the proper permissions and associated the role to the user being used by the connector?

The connector is failing to create the index on Elasticsearch, likely for a lack of permissions.

I didn’t create any role.
Pelase can you give me the link about the example in the image?
Thank you

Absolutely. Here it is:
