Unlike entity actions, action buttons are specific to individual forms and are configured directly in the Actions tab of the definition. Action buttons added to a request appear in the top toolbar on the request page.
Configuring Action Buttons
Within the Actions tab of a lab request definition, click “Add New Action” (A).

Add a Label (B) and paste the reference for the trigger or trigger set you are wanting to fire (C).

Once configured, the action button will appear within the top toolbar of the lab request.
