How can I define the ManyToManyField name in django?

I have this relationship

Class Item(models.Model):
   pass

Class Category(models.Model):
   items = models.ManyToManyField(Item)

I can define the field name as items for category and access it via category.items but I want to define a field name for Item too as item.categories rather than the default item.category

How can I achieve it?

Update

Tried

items = models.ManyToManyField(Item, related_name = "categories")

But I get

TypeError: Direct assignment to the reverse side of a many-to-many set is prohibited. Use categories.set() instead.

on Item.object.create(**data)
