Laravel pass model class as paramter in function

I have written a Controller which delete a record from the database, which is pretty straight forward. The code look like below.

public function destroy(Request $request)
    {
        try {
            MyModel::where('id', json_decode($request->get('data'),true)['id'])->delete();
            return response()->json([
                'status' => 'success',
                'message' => 'Deleted successfully'
            ]);
        } catch (\Exception $e) {
            return response()->json(['status' => 'error', 'message' => 'Something went wrong!!', 'exception_message' => $e]);
        }
    }

Now i wish to use the logic of delete at one common place, there will be many model which will have destroy function. So I wrote this

public function destroy(Request $request)
    {
        return Crud::destroy(MyModel::class, $request);
    }

Crud Class

<?php


namespace App\Helper;


use App\Http\Controllers\Controller;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Http\Request;

class Crud extends Controller
{

    public static function destroy(Model $model,Request $request)
    {
        try {
            $output = $model::where('id', $request->get('id'))->delete();
            return response()->json([
                'status' => 'success',
                'message' => 'Deleted successfully',
                'output' => $output
            ]);
        } catch (\Exception $e) {
            return response()->json(['status' => 'error', 'message' => 'Something went wrong!!', 'exception_message' => $e]);
        }
    }

}

?>

But when i call destroy function i am getting error as Type error: Argument 1 passed to App\Helper\Crud::destroy() must be an instance of Illuminate\Database\Eloquent\Model, string given,

How can i pass Laravel Model in a function.
