Laravel 6 or higher versions comatibility

[yomnamohamed93]

I am trying to upgrade my laravel app to laravel 6 but I get the following error while running composer update

- Root composer.json requires sahusoftcom/eloquent-image-mutator ^2.1.9 -> satisfiable by sahusoftcom/eloquent-image-mutator[v2.1.9, v2.2.0, v2.2.1].

- sahusoftcom/eloquent-image-mutator[v2.1.9, ..., v2.2.1] require laravel/framework ^5.1 -> found laravel/framework[v5.1.0, ..., v5.8.38] but it conflicts with your root composer.json require (^6.20).

I'm not sure if the package is compatible with versions higher than laravel 5 or not .
My current package version is 2.1.9
