 - `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.

+- `hidden` (Boolean) Determines if the app is visible in the UI (minimum coder version: v2.16).
 - `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/icon. Use a built-in icon with `"${data.coder_workspace.me.access_url}/icon/<path>"`.
 - `order` (Number) The order determines the position of app in the UI presentation. The lowest order is shown first and apps with equal order are sorted by name (ascending order).
 - `share` (String) Determines the level which the application is shared at. Valid levels are `"owner"` (default), `"authenticated"` and `"public"`. Level `"owner"` disables sharing on the app, so only the workspace owner can access it. Level `"authenticated"` shares the app with all authenticated users. Level `"public"` shares it with any user, including unauthenticated users. Permitted application sharing levels can be configured site-wide via a flag on `coder server` (Enterprise only).
