Problems adding the prerequisites for cross cluster replication

I am trying to add the prerequisites as pointed on the Tutorial: Set up cross-cluster replication | Elasticsearch Guide [7.13] | Elastic so I added to my k8s elastic yaml in the local cluster:

ccr_user:
cluster:
- manage_ccr
indices:
- names: [ 'follower-index' ]
privileges:
- monitor
- read
- write
- manage_follow_index

I am getting:
uncaught exception in thread [main]
org.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: unknown setting [cluster.ccr_user.cluster] please check that any required plugins are installed, or check the breaking changes documentation for removed settings

I added to the xpack section and I was getting:
"org.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: unknown setting [xpack.ccr_user.cluster] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"

So I am lost. Should it be part of the xpack? and if it is why is not taking it and if it is not part. What plugins I need to add?

Thanks in advance

Can you share your Elasticsearch log from startup to when you see that?
