Get access to the last object from foreign key

My models are here:

class UserToPackageMeta(models.Model):
    user = models.ForeignKey(
        User, on_delete=models.CASCADE, related_name="package_metas"
    )
    package = models.ForeignKey(
        "platforms.Package", on_delete=models.RESTRICT, related_name="user_metas"
    )


class Package(models.Model):
    platform = models.ForeignKey(
        Platform, on_delete=models.CASCADE, related_name="packages"
    )


class Platform(models.Model):
    slug = models.CharField(max_length=125, blank=True, null=True)

I want to write a query to get users based on platfrom slug on last package they have because any user can have diffrante packages:

I tried this:

users = users.filter(package_metas__package__platform=platform)

But this won’t consider only the last package for each user.
