In First Activity, take val resultLauncher using below code-

private val resultLauncher = registerForActivityResult(StartActivityForResult()) { result ->
        if (result.resultCode == Activity.RESULT_OK) {
            

            try {
                val data: Intent? = result.data

                
                val stringResponse = data?.getStringExtra("response")!!


                

            } catch (e: Exception) {
                e.printStackTrace()
            }

        }
    }

Now Call this val, where you want to make startActivityFor Result

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)


        button.setOnClickListener {
            val intent = Intent(this, SecondActivity::class.java)
            resultLauncher.launch(intent)
        }
    }

In second Activity return the value-

    private fun successResult(returnString: String) {
        val intent: Intent = intent
        intent.putExtra("response", returnString)
        setResult(Activity.RESULT_OK, intent)
        finish()
    }

    private fun cancelResult() {
        val intent: Intent = intent
        setResult(Activity.RESULT_CANCELED, intent)
        finish()
    }
