It passes all props down to the actual Action component.

Example of creating your own actions:

// AdminJS options
const AdminJSOptions = {
  resources: [
     resource,
     options: {
       actions: {
          myNewAction: {
            label: 'amazing action',
            icon: 'Add',
            inVisible: (resource, record) => record.param('email') !== '',
            actionType: 'record',
            component: AdminJS.bundle('./my-new-action'),
            handler: (request, response, data) => {
              return {
                 ...
              }
            }
          }
       }
     }
  ]
}

// ./my-new-action.jsx
import { Box } from 'adminjs'

const MyNewAction = (props) => {
  const { resource, action, record } = props
  // do something with the props and render action
  return (
    <Box>Some Action Content</Box>
  )
}
