I have neo4j node and relationship schema in neomodel as given below. Now I need to create a function so that it takes the uid of the PersonRel and delete the relationship between the two persons connected by this relationship. I couldn't find it in the documentation: <https://neomodel.readthedocs.io/en/latest/>

```
class PersonRel(StructuredRel):
    uid = StringProperty()
    created_at = DateTimeProperty(
        default=lambda: datetime.now(pytz.utc)
    )
    weight = FloatProperty()
    direction = StringProperty()

class PersonNode(StructuredNode):
    uid = UniqueIdProperty()
    label = StringProperty(required=True)
    description = StringProperty()
    related_to = RelationshipFrom("PersonNode", "related_to", model=PersonRel)
    created_at = DateTimeProperty(
        default=lambda: datetime.now(pytz.utc)
    )

```
