 - `command` (String) A command to run in a terminal opening this app. In the web, this will open in a new tab. In the CLI, this will SSH and execute the command. Either "command" or "url" may be specified, but not both.
 - `display_name` (String) A display name to identify the app. Defaults to the slug.
+- `external` (Boolean) Specifies whether "url" is opened on the client machine instead of proxied through the workspace.
 - `healthcheck` (Block Set, Max: 1) HTTP health checking to determine the application readiness. (see [below for nested schema](#nestedblock--healthcheck))
 - `icon` (String) A URL to an icon that will display in the dashboard. View built-in icons here: https://github.com/coder/coder/tree/main/site/static/icons. Use a built-in icon with `data.coder_workspace.me.access_url + "/icons/<path>"`.
 - `name` (String, Deprecated) A display name to identify the app.
