Creating table filter in a trait

I have a table filter that works perfectly when created directly in my resources, but fails when I try to move it to a trait (I have multiple resources with the same filter).

trait SoftDeleteFilter
{
    public static function softDeleteFilter()
    {
        return Filter::make('is_deleted')
            ->label('Deleted')
            ->baseQuery(fn (Builder $query) => $query->withoutGlobalScopes([
                SoftDeleteScope::class,
            ]))
            ->toggle()
            ->query(function (Builder $query, array $data): Builder {
                return $query->whereHas('activity_log', fn (Builder $query) => $query->where('activity', '=', ActionEnum::Delete));
            });
    }
}

trait SoftDeleteFilter
{
    public static function softDeleteFilter()
    {
        return Filter::make('is_deleted')
            ->label('Deleted')
            ->baseQuery(fn (Builder $query) => $query->withoutGlobalScopes([
                SoftDeleteScope::class,
            ]))
            ->toggle()
            ->query(function (Builder $query, array $data): Builder {
                return $query->whereHas('activity_log', fn (Builder $query) => $query->where('activity', '=', ActionEnum::Delete));
            });
    }
}

How I'm calling it:

->filters([
    self::softDeleteFilter()
])

->filters([
    self::softDeleteFilter()
])

Doesn't cause an error; just basically clears the table. I suspect I'm messing up something related to static methods, but I'm not sure. Can anyone point out what my mistake is? Would it be a better approach to just extend the Filter class similar to how the trashed filter extends the ternary filter class? Thanks

Solution:

Laravel macros are new to me. While trying to find documentation on them, I eventually came across Dan Harrin's recent laracasts series, and it turns out one of his videos creates a custom filter and turns it into a reusable class like I was thinking about https://laracasts.com/series/build-advanced-components-for-filament/episodes/11. So I'm going to go with that approach, but now that I know about Laravel macros, I'll definitely be spending some time learning them. Edit: while creating the class, I realized I forgot to import my SoftDeleteScope class into the trait. I didn't realize that would fail silently....

You could create a macro in the AppServiceProvider

Table::macro('withSoftDeleteFilter', fn () => 
    $this->filters([
        Filter::make('is_deleted')
        ...
    ])
);

Table::macro('withSoftDeleteFilter', fn () => 
    $this->filters([
        Filter::make('is_deleted')
        ...
    ])
);

return $table
    ...
    ->withSoftDeleteFilter()

return $table
    ...
    ->withSoftDeleteFilter()
