On laravel 10 site I have a traite with getModelTitle method defined

<?php

namespace AppLibraryTraits;


trait AppCommonTrait
{


    protected function getModelTitle(string $dataType): string
    {
        $a = Str::of($dataType)->explode('\');
        return ((count($a) === 3)) ? $a[2] : '';

    }

But I failed to call it from a static app/Data/DataObjectUser.php class :

use AppModelsPost;
use SpatieLaravelDataData;

class DataObjectUser extends Data  // extends spatie/laravel-data package
{
    use AppCommonTrait;


    public function __construct() {
        ...
    }

    public static function getFilteredData(bool $returnJson = false, bool $extendResource = false): array
    {
        return self::$dataRows;
    }

    public static function filter(): bool
    {
        $model = self::getModelTitle(Post::class);

I have error :

Non-static method AppDataDataObjectUser::getModelTitle() cannot be called statically

Object DataObjectUser called statically and I do not know if there is a way it calls traite method ?

"laravel/framework": "^10.48.7",
"spatie/laravel-data": "^4.4.1",

Thanks in advance!
