combine 2 nested dictionaries

I am trying to add an additional entry to a nested dictionary. I am able to extract the nested dictionary, append to the dictionary but can't fully figure out how to replace the nested section with the newly created one. I have a feeling there is a much easier way to do this. I will just ask what I want in the end instead of posting what I have tried and see where it goes.

I need to add an additional entry under my_team that will come in as a var:

ok: [localhost] => changed=false 
  json:
    OTHER_KEYS_1: value1
    OTHER_KEYS_2:
      value1
      key1: value1
    OTHER_KEYS_3:
      key1: value1
      key2: value2
      my_team:
      - org: Default
        team: TEAM-ONE-ADMINS
      - org: Default
        team: TEAM-ONE-USERS
      - org: Default
        team: TEAM-TWO-USERS
      - org: Default
        team: TEAM-TWO-ADMINS
      - org: Default
        team: TEAM-THREE-USERS
      - org: Default
        team: TEAM-THREE-ADMINS
    OTHER_KEYS_4: {}
    OTHER_KEYS_5:
      emailAddress: [email protected]
      givenName: User Name
    OTHER_KEYS_6:
      key1: value1
  msg: OK (7003 bytes)

Solution

Q: "Add an additional entry under my_team."

A: Given simplified data

    data:
      k1: v1
      k2: v2
      k3:
        key1: value1
        key2: value2
        my_team:
          - {org: default, team: team_one}
          - {org: default, team: team_two}

Declare what you want to add

    data_add:
      k3:
        my_team:
          - {org: default, team: team_three}

and combine the dictionaries

  result: "{{ [data, data_add]|combine(recursive=True, list_merge='append') }}"

gives the dictionary with an additional entry under my_team

  result:
    k1: v1
    k2: v2
    k3:
      key1: value1
      key2: value2
      my_team:
      - {org: default, team: team_one}
      - {org: default, team: team_two}
      - {org: default, team: team_three}
