How restrict specific rows to be deleted

Hello, I am creating role resources in Filament and want to prevent the deletion of the admin row from the role table. How can I do that?

Here is my current resource:

<?php

namespace App\Filament\Resources;

use App\Filament\Resources\RoleResource\Pages;
use App\Filament\Resources\RoleResource\RelationManagers;
use Filament\Forms;
use Filament\Forms\Components\TextInput;
use Filament\Forms\Form;
use Filament\Resources\Resource;
use Filament\Tables;
use Filament\Tables\Actions\DeleteAction;
use Filament\Tables\Actions\EditAction;
use Filament\Tables\Columns\TextColumn;
use Filament\Tables\Filters\BaseFilter;
use Filament\Tables\Table;
use Illuminate\Database\Eloquent\Builder;
use Illuminate\Database\Eloquent\SoftDeletingScope;
use Spatie\Permission\Models\Role;

class RoleResource extends Resource
{
    protected static ?string $model = Role::class;

    protected static ?string $navigationIcon = 'heroicon-o-rectangle-stack';

    public static function form(Form $form): Form
    {
        return $form
            ->schema([
                TextInput::make('name')
                    ->minLength(3)
                    ->maxLength(50)
            ]);
    }

    public static function table(Table $table): Table
    {
        return $table
            ->columns([
                TextColumn::make('name')->searchable()
            ])
            ->filters([
                BaseFilter::make('name')
            ])
            ->actions([
                EditAction::make(),
                DeleteAction::make('admin'),
            ])
            ->bulkActions([
                Tables\Actions\BulkActionGroup::make([
                    Tables\Actions\DeleteBulkAction::make(),
                ]),
            ]);
    }

    public static function getRelations(): array
    {
        return [
            //
        ];
    }

    public static function getPages(): array
    {
        return [
            'index' => Pages\ListRoles::route('/'),
            'create' => Pages\CreateRole::route('/create'),
            'edit' => Pages\EditRole::route('/{record}/edit'),
        ];
    }
}
