MQTT script payload

Hi.
I’m having some problems with a mqtt.publish script for the xiaomi smoke detector.
I want to write a script to test the detector as it is explained here.
However, I can’t make the payload string to work.
I’m sure I’m missing a quotation mark or something like that, but I’m clueless right now.
If anyone could help me, I would appreciate it very much.

smoke_test:
  alias: Smoke test
  sequence: 
    service: mqtt.publish
    data:
      topic: zigbee2mqtt/0x000000000000/set
      payload: "{"selftest": ""}"
