How to Decode out_of_date_subscribed_caches from GC clientWelcome Message?

[FadingSky]

I'm currently trying to decode the out_of_date_subscribed_caches from the CS2 GC clientWelcome message. However, I don’t know where to find the definitions or type_ids needed to parse the object data. I noticed that Node-GlobalOffensive is only parsing type_id 1.

I want to retrieve the current XP of the account as well as additional information. Therefore, I would like to parse all type_ids if possible.

Here is the out_of_date_subscribed_caches:

[
  {
    objects: [
      {
        object_data: [
          new Uint8Array([8, 5, 24, 1, 32, 144, 250, 241, 198, 6, 40, 2]),
        ],
        type_id: 2,
      },
      {
        object_data: [
          new Uint8Array([8, 246, 220, 169, 198, 6, 16, 0, 24, 238, 165, 128, 128, 128, 128, 128, 128, 240, 1, 24, 197, 185, 213, 236, 172, 1, 24, 191, 128, 196, 169, 128, 128, 128, 128, 240, 1, 24, 199, 185, 213, 236, 172, 1]),
        ],
        type_id: 4,
      },
      {
        object_data: [
          new Uint8Array([8, 238, 146, 176, 198, 6, 16, 200, 1, 24, 224, 93, 24, 224, 93, 24, 224, 93, 24, 224, 93, 24, 224, 93]),
        ],
        type_id: 6,
      },
      {
        object_data: [
          new Uint8Array([8, 0, 101, 144, 66, 211, 104, 104, 131, 130, 128, 128, 6, 112, 5, 120, 5]),

          new Uint8Array([8, 164, 128, 244, 131, 128, 128, 128, 128, 240, 1, 16, 188, 197, 224, 214, 6, 24, 133, 128, 128, 128, 12, 32, 36, 56, 1, 64, 24, 72, 8, 98, 8, 8, 6, 26, 4, 0, 0, 250, 66, 152, 1, 4]),

They're likely to be protobuf objects that are defined in the CS2 protobufs. I don't have any source off-hand to map type_ids to protobuf definitions; your best bet is likely to just try parsing data using various definitions and see what looks right.
