Typing the Store when imported to typescript pinia vue

How can I type the Store when imported to typescript pinia vue. Do I need to type it at all?

// Component

<p>{{ storeForm.firstName }}</p>  // getting an error "Property 'storeForm' does not exist on type"


// Store

export default {
  setup() {
    const storeForm = useForm();  // Probabilly type it at this line
  }
