Filtering arrays inside $map

Hi I am trying to filter out a property from json while building result inside $map

{
  "nodes": [
    {
      "field_type": "a",
      "text": "test_a"
    },
    {
      "field_type": "b",
      "text": "test_b"
    },
    {
      "field_type": "b",
      "text": "test1_c"
    }
  ]
}

I want to return only a and c. and remove b. this is what I have so far: https://try.jsonata.org/Oz9umE30F Thanks
