I want to Import new library to my project. this is what I want to import

composer require barryvdh/laravel-dompdf

but, my project refuse this package.and this is error what I get

Info from https://repo.packagist.org: #StandWithUkraine
Using version ^1.0 for barryvdh/laravel-dompdf
./composer.json has been updated

  Problem 1
    - Root composer.json requires barryvdh/laravel-dompdf ^1.0 -> satisfiable by barryvdh/laravel-dompdf[v1.0.0].        
    - barryvdh/laravel-dompdf v1.0.0 requires illuminate/support ^6|^7|^8|^9 -> found illuminate/support[v6.0.0, ..., v6.20.44, v7.0.0, ..., v7.30.6, v8.0.0, ..., v8.83.5, v9.0.0, ..., v9.5.1] but these were not loaded, likely because it conflicts with another require.


Installation failed, reverting ./composer.json and ./composer.lock to their original content.
