Laravel – How to set up index resource to include the inverse one-to-many model?

I have two models, one for Company and one for Invoice. There is a one-to-many relationship as the company can have many invoices.

I am now setting up the index page for the invoices, but in the index page, I want to display the company name. How can I set up the controller if I don’t yet have the ID for the company?

This is what I have so far on my invoice controller

public function index()
    {
        
        return Inertia::render('Invoices/Index', [
            'invoices' => Invoice::all(),
        ]);

    }

That passes all the invoices to the correct route, but I don’t know how to pass the company data.

My Invoice model looks like this – and the table has a company_id field

public function company(){

     return $this->belongsTo(Company::class);

}

and my Company model looks like this

public function invoices(){

    return $this->hasMany(Invoice::class);

}

The company migration is this

public function up()
    {
        Schema::create('companies', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('website')->nullable();
            $table->string('address_1')->nullable();
            $table->string('address_2')->nullable();
            $table->string('city')->nullable();
            $table->string('post_code')->nullable();
            $table->string('country')->nullable();
            $table->timestamps();
        });
    }

and the invoice migration is this

public function up()
    {
        Schema::create('invoices', function (Blueprint $table) {
            $table->id()->from(8023052);
            $table->integer('company_id')->unsigned();
            $table->integer('invoice_company_id');
            $table->text('description');
            $table->string('status');
            $table->decimal('subtotal', 8, 2);
            $table->decimal('tax', 8, 2);
            $table->decimal('total', 8, 2);
            $table->date('invoice_date');
            $table->date('due_date');
            $table->timestamps();
        });
    }
