Zigbee quirk: rename a Switch

I want to rename a Switch.
I want to add something like

        self._update_attribute(
            self.attributes_by_name["description"].id, "Child lock"
        )

to

class ZONNSMARTChildLock(ZONNSMARTHelperOnOff):
    """On/Off cluster for the child lock of the heating thermostats."""

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.endpoint.device.child_lock_bus.add_listener(self)

    def get_attr_val_to_write(self, value):
        return {ZONNSMART_CHILD_LOCK_ATTR: value}

But there is no “description” in this class.

Easiest way is to simply rename it in HA (click the entity name > cog icon > populate the name field)
