typing error in composition api for $can

[morteza-mortezai]

Hi,

I'm using $can in component and I'm getting this error

Property '$can' does not exist on type '{ $: ComponentInternalInstance; $data: {} ....

package.json

I think this is not related to this package.

However, in any file d.ts you can do this:

declare module 'vue' {
  interface ComponentCustomProperties {
    $currentUser: CurrentUser;
  }
}

In this example I declared a variable that stores the current user.

I hope it can help
