Resource locator
The resource locator element helps users find a specific resource in an external service, such as a card or label in Trello.
The following options are available:
- ID
- URL
- List: allows users to select or search from a prepopulated list. This option requires more coding, as you must populate the list, and handle searching if you choose to support it.
You can choose which types to include.
