Set an action guard's modal properties

[ChrystianFerreira]

Taking a look at the design system's storybook, I learned that you should be able to set a modals variant, title, subtitle and other props.

Using an action guard, I am only able to set a value for the modal's title. Is it possible to achieve the same level of customization in my custom action's guard?

Example code of my guard:

{
  resource: Event,
  actions: {
    myCustomAction: {
      actionType: 'record',
      component: false,
      handler: (request, response, context) => {
        // ...
      },
      variant: 'info',
      guard: 'This sets the modal title',
    },
  }
},
