I think that this suggestion does not work. I think that we need something with parameters like in Classic UI:

@mbarde Yes, we need a full message with params, as @erral is suggesting.

See the example in the docs:

function () {
  const messages = defineMessages({
    greeting: {
      id: 'app.greeting',
      defaultMessage: 'Hello, {name}!',
      description: 'Greeting to welcome the user to the app',
    },
  })

  return intl.formatMessage(messages.greeting, {name: <b>Eric</b>})
}

Last week I tried unsuccessfully to build such messages trying to keep existing HTML, but it should be possible like @tiberiuichim suggests
