 ```bash
-evergreen patch -p ai-ml-pipelin-testing --param REPO_ORG="<my-org>" --param REPO_BRANCH="<my-branch>" -y "<my-message>"
+evergreen patch -p ai-ml-pipeline-testing --param REPO_ORG="<my-org>" --param REPO_BRANCH="<my-branch>" -y -d "<my-message>"

+evergreen patch -p ai-ml-pipeline-testing --param REPO_ORG=caseyclements --param REPO_NAME="langchain-mongodb" --param REPO_BRANCH="INTPYTHON-629" -y -d "Increased retries to 4."
