How to pass a token to a protected route (a method in class) in Laravel

I am writing phpunit tests in Laravel.

I log in successfully into the application using the folloiwng code:

$response = $this->json('POST', 'login', 
      [
        'user_name'  =>  $username,
        'password'  =>  $password ,
     ]);

 $response->assertStatus(200); // This is ok and passes the test -- is green

I get the following results when I dd $response:

+original: array:5 [
  "status" => 200
  "data" => array:4 [
    "token_type" => "Bearer"
    "expires_in" => 7200
    "access_token" =>     "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiJ9.eyJhdWQiOi...snipped"
    "refresh_token" => "def50200eb65ae708701e58c732140ea2efca0083...snipped"

When I invoke a protected method called doSomething as follows

$token = "Bearer and I hardcode the access token above"

$response = $this->json('POST', 'doSomething', [
        'token' => $token
     ]);
     
     dd($response);

I get the following message:

 "{"status":401,"message":"Unauthenticated.Token invalid or expired. Please login or refresh token to   proceed"}"

Question:

1. How can I pass the valid token I received from the successful login to the doSomething method and all the other routes I want to test?
