How can I filter distinct users in django

I'm trying to build a messaging app. Here's my model,

class Message(models.Model):
sender = models.ForeignKey(User, related_name="sender")
receiver = models.ForeignKey(User, related_name="receiver")
msg_content = models.TextField()
created_at = models.DateTimeField(auto_now_add=True)

This is what I tried in view,

data = Message.objects.filter(Q(sender=request.user) | Q(receiver=request.user))

In the template,

{% for abc in data %}
{{ abc.receiver }}

{% endfor %}

Here i wants to filter the distinct receivers and re-order them based upon the fact that to whom `request.user` sent new message recently (as we see on social media platforms). How can I do that?

I'm hanged with this code from 1 month, I will be very thankful with every little help :)

What I have tried:

data = Message.objects.filter(Q(sender=request.user) | Q(receiver=request.user)).values('receiver').distinct().order_by()

Also I tried,

data = Message.objects.filter(Q(sender=request.user) | Q(receiver=request.user))
receiver_list =
data.filter(sender=request.user).order_by('created_at').distinct('receiver')

In the template, use an if condition that checks your receiver and sender for a particular message.
Something like

Python

{% if abc.receiver == request.user %}
# this means that the current user is the receiver
{% endif %}

Similarly you should be able to do it for abc.sender.

You'll need to pass current logged in user in the context(in your view).
