As pointed out here by katherine: https://github.com/openshift/openshift-docs/pull/29411#discussion_r579432427 Change the heading of this module to reflect the procedure. Explore if, 'Logging in to the Argo CD instance using your Openshift Credentials' makes sense.
Also fix all the comments on this module in the PR. Reconcile with the initial content provided by devs, dig for more information if required, test and then document it. This needs to go into the Getting started with OpenShift GitOps assembly.
