Adding new Blade directives (Prefix and Suffix fields?) [PhpStorm]

Question

I am using Windows 7, PhpStorm 2018.1.3 and Laravel 5.6. I have installed spatie/laravel-permission and I would like to add the following Blade directives in PhpStorm:

https://github.com/spatie/laravel-permission#using-blade-directives

For example:

@role('writer')
    I am not a writer...
@endrole

and:

@hasallroles($collectionOfRoles)
...
@endhasanyrole

So:

1. I go to: File / Settings / Languages & Frameworks / Blade / Directives
2. Click on + (Add directive) button
3. Enter Name
4. check has parameter

... and now what? What should I enter in Prefix and Suffix fields for these particular cases (@role('writer') and @hasallroles($collectionOfRoles))?
