CircleCI run multi line command

Excerpt from a CircleCI config file:

deploy:
  machine:
    enabled: true
  steps:
    - run:
        name: AWS EC2 deploy
        command: |
          ssh -o "StrictHostKeyChecking no" ubuntu@xxx.xxx.xxx.xxx "cd ~/circleci-aws; git pull; npm i; npm run build; pm2 restart build/server

How can I break the command into multiple lines? Tried below syntax, but it only runs the first command:

deploy:
  machine:
    enabled: true
  steps:
    - run:
        name: Deploy
        command: |
          ssh -o StrictHostKeyChecking=no ubuntu@xxx.xxx.xxx.xxx
          cd ~/circleci-aws
          git pull
          npm i
          npm run build
          pm2 restart build/server

You'll need to pass those other commands as args to a shell (like bash):

ssh -o StrictHostKeyChecking=no ubuntu@xxx.xxx.xxx.xxx bash -c '
      cd ~/circleci-aws
      git pull
      npm i
      npm run build
      pm2 restart build/server'
