Can't toggle alarms and reminders permission

I have app which set alarms. I use this code to ask user for permission:

Intent intent = new Intent(
"android.settings.REQUEST_SCHEDULE_EXACT_ALARM",
 Uri.parse("package:"+ getPackageName())
);
 someActivityResultLauncher.launch(intent);

In manifest I added permission:

<uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM"/>

When I click the button which launch the intent I can see:

enter image description here

But I can't toggle button with permission and I don't know why.

// Button click for check permission 
 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S_V2) {
                        hasPermission(AlarmActivity.this);
                    }
// 2 Number code

 @RequiresApi(api = Build.VERSION_CODES.S_V2)
    void hasPermission(@NonNull Context context) {
        AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S_V2) {

            // it depends on the manifest permission, just alike the toggle does.
            if (!alarmManager.canScheduleExactAlarms()) {
                startActivityForResult.launch(new Intent(
                        Settings.ACTION_REQUEST_SCHEDULE_EXACT_ALARM,
                        Uri.parse("package:" + getPackageName())
                ));
            }

            // one can only disable the permission, when the manifest requested it.

        }
    } 
// 3 Number code 

ActivityResultLauncher<Intent> startActivityForResult = registerForActivityResult(
            new ActivityResultContracts.StartActivityForResult(), (ActivityResult result) -> {
                if (result.getResultCode() == RESULT_OK) {

                }
            });

It will return isGranted = true when the permission is being requested the AndroidManifest.xml.

<uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM"/>

And actually, the intent is Settings.ACTION_REQUEST_SCHEDULE_EXACT_ALARM:

ActivityResultLauncher<Intent> startActivityForResult = registerForActivityResult(
        new ActivityResultContracts.StartActivityForResult(), (ActivityResult result) -> {
            if (result.getResultCode() == RESULT_OK) {}
        });

@RequiresApi(api = Build.VERSION_CODES.S_V2)
void hasPermission(@NonNull Context context) {
    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S_V2) {

        // it depends on the manifest permission, just alike the toggle does.
        if (! alarmManager.canScheduleExactAlarms()) {

        }

        // one can only disable the permission, when the manifest requested it.
        startActivityForResult.launch(new Intent(
                Settings.ACTION_REQUEST_SCHEDULE_EXACT_ALARM,
                Uri.parse("package:" + getPackageName())
        ));
    }
}

Listen for broadcast action AlarmManager.ACTION_SCHEDULE_EXACT_ALARM_PERMISSION_STATE_CHANGED.

And there's also permission USE_EXACT_ALARM, when targeting API 33 onwards.

See behavioral changes: exact alarm permission.
