 ```sh
-tkn pipeline start automerge-pipeline -r source-repo=gitops-repo -r pr=pull-request -p github-config=promoteconfigmap -p github-secret=github-secret --showlog
+tkn pipeline start automerge-pipeline -r source-repo=gitops-repo -r pr=pull-request -p github-config=promoteconfigmap -p github-secret=github-secret --showlog -s my-sa
 ```
