How to create and use filterFormData in sample code example?

[sergeynilov]

In laravel 11.09 / livewire 3.5 app I added leandrocfe/filament-apex-charts ^3.1 package
but reading docs how to add custom filter I did not find what is filterFormData in sample code example?

Is it class created with command like :

php artisan livewire:form filterFormData
from livewire?

I have some livewire expierence, but that is confusing for me. Please point to example how to create and use this form ?
