How to get friends of friends (mutual friends) - Django

I have been able to get the list of all users and also implement sent friend request (following/follower). Now, how do I get mutual friends(following/followers)? For example; if both user have an existing friend in common.

Below code is what I have tried, but not displaying mutual friends. What am I doing wrong and how can I get it done correctly?

class Profile(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL,on_delete=models.CASCADE,blank=True,null=True) 
    profile_pic = models.ImageField(upload_to='UploadedProfilePicture/', default="ProfileAvatar/avatar.png", blank=True)
    following = models.ManyToManyField(
        'Profile',  # Refers to the User model itself
        symmetrical=False,  # If A follows B, B doesn't automatically follow A
        related_name='followers',  # Reverse relationship: get followers of a user
        blank=True,
    )


def FollowingView(request):
    page_title = "Following"

    # All users following posts
    posts = Post.objects.filter(
        Q(poster_profile=request.user)|
        Q(poster_profile__profile__followers__user=request.user)).order_by("?").distinct()

    # All account users
    profile_users = Profile.objects.exclude(
        Q(user=request.user))

    # Mutual Followers
    all_following = request.user.profile.following.values_list('pk', flat=True)
    mutual_followers = Profile.objects.filter(pk__in=all_following)

friends_of_friends = Profile.objects.filter(followers__followers__user=request.user)

friends_of_friends = Profile.objects.filter(
    followers__user=request.user
).filter(
    followers__user=C
)

my_profiles = Profile.objects.prefetch_related(
    Prefetch(
        'following',
        Profile.objects.filter(followers__user=request.user),
        to_attr='friends_in_common'
    ),
)
