OAuth Toolkit Requiring Authorization

I am using Django OAuth toolkit and the following code for OAuth implementation.

import requests
from django.http import JsonResponse
from django.shortcuts import redirect, render
from django.contrib.auth import authenticate, login, logout
from django.contrib.auth.decorators import login_required
from .forms import AuthenticationForm, UserProfileForm
from .models import UserProfile
from oauth2_provider.models import get_application_model
import base64
    Application = get_application_model()
    def oauth_login(request):
        app = Application.objects.get(name="App")
        redirect_uri = request.POST.get("redirect_uri", "http://test.com:8002/redirect.html")

        authorization_url = (
            f"http://test.com:8000/o/authorize/?client_id={app.client_id}&response_type=code&redirect_uri={redirect_uri}"
        )
        return redirect(authorization_url)

    def oauth_callback(request):
        code = request.GET.get("code")

        if not code:
            return JsonResponse({'error': 'missing_code', 'details': 'Missing code parameter.'}, status=400) 

        token_url = "http://test.com:8000/o/token/"
        client_id = Application.objects.get(name="App").client_id
        client_secret = Application.objects.get(name="App").client_secret
        redirect_uri = request.GET.get("redirect_uri", "http://test.com:8002/redirect.html")

        data = {
            "grant_type": "authorization_code",
            "code": code,
            "redirect_uri": redirect_uri,
            "client_id": client_id,
            "client_secret": client_secret,
        }

        headers = {
            'Content-Type': 'application/x-www-form-urlencoded',
            'Authorization': f'Basic {base64.b64encode(f"{client_id}:{client_secret}".encode()).decode()}',
        }

        response = requests.post(token_url, data=data, headers=headers)
        tokens = response.json()
        print(tokens)
        if response.status_code != 200:
            return JsonResponse({'error': 'token_exchange_failed', 'details': tokens}, status=response.status_code)

        request.session['access_token'] = tokens['access_token']
        request.session['refresh_token'] = tokens['refresh_token']

        return JsonResponse(tokens)

The issue is that it only works if the user is already logged in to the /admin site. I am not sure why is this behaviour. Can someone explain why I need to be in the Django Administration panel to enable the OAuth functionality?
