Get scopes for installed apps

Ask: To get a list of all apps installed on my workspace along with their scopes.

Issue One way to look at: There are multiple apis but they don't cross over to get the complete picture.

- We have `/api/v2/oauth/tokens` which returns scopes being used by an OAuth client. Great.

{
  "tokens": [
    {
      "client_id": 41,
      "created_at": "2009-05-13T00:07:08Z",
      "expires_at": "2011-07-22T00:11:12Z",
      "id": 223443,
      "refresh_token": "af3t24tfj34h43s...",
      "scopes": [
        "read"
      ],
      "token": "af3345kdj3",
      "url": "https://example.zendesk.com/api/v2/tokens/223443.json",
      "used_at": "2010-01-22T00:11:12Z",
      "user_id": 29
    },

- Then we have `/api/v2/oauth/clients/{oauth_client_id}` which doesn't contain application id its associated with:

{
  "client": {
    "company": "Zendesk",
    "created_at": "2009-05-13T00:07:08Z",
    "description": "Zendesk Test Client",
    "id": 223443,
    "identifier": "test_client",
    "name": "Test Client",
    "redirect_uri": [
      "https://example.com/callback"
    ],
    "secret": "af3t24tfj34h43s...",
    "updated_at": "2011-07-22T00:11:12Z",
    "url": "https://example.zendesk.com/api/v2/clients/223443.json",
    "user_id": 29
  }
}

Issue another way to look at: Now try getting the same information via `/api/v2/apps/installations` it returns list of all the apps installed. Great.

{
  "installations": [
    {
      "app_id": 218618,
      "collapsible": true,
      "created_at": "2020-06-11T06:12:48Z",
      "enabled": true,
      "group_restrictions": [],
      "has_incomplete_subscription": false,
      "has_unpaid_subscription": null,
      "id": 361234573552,
      "paid": null,
      "pending_installation": true,
      "pending_job_id": "587986abda901cde3873697585091dab",
      "plan_information": {
        "name": null
      },
      "product": "support",
      "recurring_payment": false,
      "redirect_path": "/support/apps/manage",
      "role_restrictions": null,
      "servable": true,
      "settings": {
        "attachment_tag": "has_attachment",
        "blacklist": null,
        "items_per_page": "6",
        "name": "Attachment Manager",
        "new_attachment_tag": "has_new_attachment",
        "title": "Attachment Manager",
        "whitelist": null
      },
      "stripe_account": "acct_1CyabcGO5FKrIYc5",
      "stripe_publishable_key": "pk_live_zMw5abcdYBbd6axDbyrzrRl9",
      "updated": "20200305221223",
      "updated_at": "2020-06-11T06:12:48Z"
    }
  ]
}

However there doesn't seem to be any way to tie the installation to > oauth client > token
