 ### Preview deploy on pull request
 This action will deploy branches using the `on: pull_request: types: ['opened', 'edited', 'synchronize', 'closed']` trigger as `https://${DE_HOST}/${APP_NAME}-${event_number}`, e.g. if you are deploying an app called `inventory-analytics` to `example.plotly.host` and your PR number is `15`, the deploy preview would be available at `https://example.plotly.host/inventory-analytics-15` and would be redeployed on every new commit to that PR.
