Run commands in a pipeline to another, non-default k8s cluster

We had one k8s cluster (cluster-1) defined in GL pipeline. Then I added another one (cluster-2 - still using deprecated way: Deploy to a Kubernetes cluster with cluster certificates).

Then I triggered pipeline and got this:

This job is deployed to [cluster-2](https://..../..../..../-/environments/129) using
cluster [cluster-1](https://.../.../.../-/clusters/19) and namespace namespace-1.

So it is being deployed to the cluster-1 and not to cluster-2 (where I want it to be deployed).
In the piepline I have the following settings for this job:

  environment:
    name: cluster-2
    url: https://............

but it doesn’t help.

How do I point the deployment to the cluster-2 ?
