How to output objects in Django with filtering if ManyToMany matches?

Question

Django

There is a problem in the implementation of the code.

class Course(models.Model):
    title = models.CharField("Название курса", max_length=36)
    description = models.TextField("Описание курса", max_length=60)
    author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='author')
    pubdate = models.DateTimeField("Время создания")
    preview = models.ImageField(upload_to='media/preview/')
    duration = models.PositiveIntegerField("Продолжительность курса в часах", validators=[MaxValueValidator(999)])
    amount = models.PositiveIntegerField("Количество лекций в курсе", validators=[MaxValueValidator(999)])
    category = models.ForeignKey(Category, verbose_name="Категория", on_delete=models.CASCADE)
    price = models.PositiveIntegerField("Цена", validators=[MaxValueValidator(99999)])
    lessons = models.ManyToManyField(Lesson, verbose_name="Уроки", blank=True)
    owners = models.ManyToManyField(settings.AUTH_USER_MODEL, verbose_name="Владельцы", blank=True, related_name='owners')

The goal is this: to make a page for each user where all purchased courses will be stored. Such users who bought the course are called "Owners" (owners).
I can't make the function of displaying and filtering so that courses are on these pages only for those who bought them.
Thanks in advance for your help.
