The --filter option works with single filters, each a JSON object, but in the UI, the command palette copies all the filters in an array of objects like:

[
  {
    "key": "user_agent.name",
    "operator": "is",
    "value": "dash0-cli"
  },
  {
    "key": "service.name",
    "operator": "is_one_of",
    "values": [
      "api"
    ]
  }
]

It should be possible to pass the array to --filter like if each object in it had been passed to separate --filter arguments.
