Filter content request by related objects

Question

I am trying to use Contentful in the current project, and I am trying to figure out how to filter the results of my query based on the field in the linked object.

My top level object contains a link defined as such:

  "name": "Service_Description",
  "fields": [
{
  "name": "Header",
  "id": "header",
  "type": "Link",
  "linkType": "Entry",
  "required": true,
  "validations": [
    {
      "linkContentType": [
        "offerGeneral"
      ]
    }
  ],
  "localized": false,
  "disabled": false,
  "omitted": false
},

This header field refers to another type of content that has this definition:

  "fields": [
{
  "name": "General",
  "id": "general",
  "type": "Link",
  "linkType": "Entry",
  "required": true,
  "validations": [
    {
      "linkContentType": [
        "genericGeneral"
      ]
    }
  ],
  "localized": false,
  "disabled": false,
  "omitted": false
},

which then refers to the lower level:

"fields": [{
  "name": "TagList",
  "id": "tagList",
  "type": "Array",
  "items": {
    "type": "Link",
    "linkType": "Entry",
    "validations": [
      {
        "linkContentType": [
          "tag"
        ]
      }
    ]
  },
  "validations": []
}

where tagList is an array of tags that this piece of content can have.

I want to be able to run a request from a top-level object that says to get me the X number of these Service_Description content entries, where it contains a tag from the provided tag list.

In PostMan, I worked with this:

https://cdn.contentful.com/spaces/{SPACE_ID}/entries?access_token={ACCESS_TOKEN}&content_type=serviceDescription&include=3

I am trying to add a filter something like this:

fields.header.fields.general.fields.tagList.sys.id%5Bin%5D={TAG_SYS_ID}
