I can't get the notifications by i.d after saving it as a many to many field

Question

I have previously figured out how to send and save notifications by many to many fields to send to users, now i can't specifically call the notifications by current user logged in i.d.

Models.py

class Notifications(models.Model):

 id=models.AutoField(primary_key=True)
 sent_to = models.ManyToManyField(CustomUser)
 message = models.TextField(null=True)
 message_reply = models.TextField(null=True)
 created_at=models.DateTimeField(auto_now_add=True)
 updated_at=models.DateTimeField(auto_now=True)

The notifications_sent_to is the created table after I created the many to many save

Notifications_sent_to table (which is not created in the models)

Notifications table (which stores the message)

Views.py

def add_notification(request):

notifs = Notifications.objects.all()
users = CustomUser.objects.filter(is_staff=True)

if request.method == 'POST':
    form = AddNotifForm(request.POST)
    if form.is_valid():
        instance = form.save(commit=False)
        instance.message_reply = "none"
        instance.save()
        form.save_m2m()
        sent_to = form.cleaned_data.get('sent_to')
        messages.success(request, f'Message has been successfully sent .')
        return redirect('add_notif')
else:
    form = AddNotifForm()

context={

    'notifs' : notifs,
    'form' : form,
    'users' : users,
}

template_name ='main-admin/add-notif.html'
return render(request, template_name, context)

Forms.py

class AddNotifForm(forms.ModelForm):

sent_to = forms.ModelMultipleChoiceField(
        queryset=CustomUser.objects.filter(is_staff=True).exclude(is_superuser=True),
        widget=forms.CheckboxSelectMultiple,
        required=True)

class Meta: 
    model = Notifications
    fields = ['sent_to', 'message']

Templates view

{% for sent_to_users in sent_to_users %}
    <tr>
       <td>{{ sent_to_users.id }}</td>
       <td>{{ sent_to_users.sent_to }}</td>
       <td>{{ sent_to_users.message }}</td>
       <td>
       {% if sent_to_users.message_reply == "none" %}
       <button type="button" class="btn btn-primary reply_open_modal" data-bs-toggle="modal" data-bs-target="#replyModal">Reply</button>
       {% else %}
       {{ sent_to_users.message_reply }}
       {% endif %}
       </td>
       <td>{{ sent_to_users.created_at }}</td>
       </tr>
       {% endfor %}
