How to create Typescript interface that reflects firestore structure

Question

Good morning,

I’m getting data from firebase firestore with a structure that I’m having trouble representing as a model in Typescript, that is, an interface. I made a JSON representation to illustrate the structure:

[
    {
      "20229622": [
        {
            "info": [
                {
                    "46468999": {
                        "taskName": "Project Management",
                        "totalTaskHours": "1589.4"
                    },
                    "78945556": {
                        "taskName": "Management",
                        "totalTaskHours": "988"
                    }
                }
            ],
            "done": [
                {
                    "46468999": {
                        "done": "True"
                    },
                    "78945556": {
                        "done": "False"
                    }
                }
            ]
        }

      ],
      "90220622": [
        {
            "info": [
                {
                    "46418909": {
                        "taskName": "Interface",
                        "totalTaskHours": "189"
                    },
                    "98940556": {
                        "taskName": "Backend",
                        "totalTaskHours": "90"
                    }
                }
            ],
            "done": [
                {
                    "46418909": {
                        "done": "True"
                    },
                    "98940556": {
                        "done": "False"
                    }
                }
            ]
        }
      ]
    }
  ]

My biggest difficulty is in relation to the id’s that are automatically generated numbers by the firestore. I ask you to help me create an interface that reflects this structure, or give me some hint, especially on the issue of id’s.
