Retrofit or Okhttp never called the link

Question

So I got a problem, When the Main Page is shown, it's supposed to call the API to get the data from it. But, the API never called. What I find strange is, that before Main Page, there is a login page that successfully called the API for login. But, on Main Page, the Retrofit/Okhttp never called the Page to get the data. Do you guys know what's wrong? Here's my code screenshot:

class MainActivity : AppCompatActivity() {
    private lateinit var bind: ActivityMainBinding
    private lateinit var storyAdapter: StoryAdapter

        ViewModelFactory(this, application)
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        bind = ActivityMainBinding.inflate(layoutInflater)
        setContentView(bind.root)


        showLoadingProcess(true)
        displayStories()
        bind.floatingActionButton.setOnClickListener {
            startActivity(Intent(this, AddStoryActivity::class.java))
        }
        supportActionBar?.setTitle(R.string.app_name)
    }

    override fun onCreateOptionsMenu(menu: Menu): Boolean {
