How to update the fimware of Sonoff SNZB-02D?

I have Sonoff SNZB-02D with firmware 1.0.9, but I want to install the new version of 2.0.

I’ve tried this in configuration.yaml:

zha:
  zigpy_config:
    ota:
      extra_providers: [{'type': 'sonoff'}]

But it does nothing.

I’ve also tried to execute this action:

data:
  ieee: 0c:ef:f6:ff:fe:68:68:34
  endpoint_id: 1
  cluster_type: out
  command_type: client
  cluster_id: 25
  command: 0
  args:
    - 0
    - 100
action: zha.issue_zigbee_cluster_command

The action itself was successful, but the software did not update.

Is there a working way to update firmware?

Would it work if I buy a Sonoff Bridge Pro ZB (eWeLink), pair SNZB-02D with it, update via smartphone, reset, and connect it back to HA?
