Trying to parse data from JSON for template sensor

Configuration
1

I’m trying to see if it’s possible to create a template sensor that shows the " Id " of a given set of movies in my collection. I started with a REST API call in Postman ( GET http://192.168.1.240:8096/emby/items?Recursive=true&IncludeItemTypes=Movie&Genres=comedy ) to get the following response that shows all of the “Comedy” movies in my collection (obviously I’ve only used two titles in the example below):

{
    "Items": [
        {
            "Name": "2 Guns",
            "ServerId": "3f4c3108cb47442e9b058ad01a1e2cd4",
            "Id": "1889",
            "RunTimeTicks": 65553700000,
            "IsFolder": false,
            "Type": "Movie",
            "ImageTags": {
                "Primary": "288697e9e3bc17add9691f67bc57df1b",
                "Logo": "0902d40c7a4678ee253c4264e594e7f8",
                "Thumb": "92ed6767d69ade3a8d399fdf13da21b2"
            },
            "BackdropImageTags": [
                "ae5ada4506b7ec58cb46d17d1441047a"
            ],
            "MediaType": "Video"
        },
        {
            "Name": "21 & Over",
            "ServerId": "3f4c3108cb47442e9b058ad01a1e2cd4",
            "Id": "1890",
            "RunTimeTicks": 55864950000,
            "IsFolder": false,
            "Type": "Movie",
            "ImageTags": {
                "Primary": "07f25c808e4451ab0cc26a14918a58a6",
                "Logo": "fb814f5628c1864db3a41f952d7330f5",
                "Thumb": "eacbb7135ab24261d75dc5b29c5fc658"
            },
            "BackdropImageTags": [
                "9bd4efb96311fd6c0a184dd1f4684709"
            ],
            "MediaType": "Video"
        },

For another part of the system I’m working on I have a sensor that gets the session ID from the current Emby instance:

- platform: command_line
  name: embysession_livingroom
  command: "curl -H \"Content-Type: application/json\" -H \"X-Emby-Token: xxxxxxxxx\" -X GET \"http://192.168.1.240:8096/emby/Sessions\" | jq -r '.[] | select(.DeviceId==\"Livingroom\") | .Id'"
  scan_interval: 4

Using this, the sensor returns the value of the session ID as a string.

I’ve tried adopting this for the show ID sensor I’d like to build, but I don’t really know much about using these commands, so I’d appreciate it if someone here might be able to help me (if it’s at all possible). I know the following is incorrect, but it’s as far as I’ve got so far… The sensor just says “Unknown”.

- platform: command_line
  name: emby_movies_comedy
  command: "curl -H \"Content-Type: application/json\" -H \"X-Emby-Token: xxxxxxxxx\" -X GET \"http://192.168.1.240:8096/emby/items?Recursive=true&IncludeItemTypes=Movie&Genres=comedy\" | jq .Id'"
  scan_interval: 4

My end goal is to ideally have a sensor that lists the ID’s of all of my comedy movies in a single comma-separated string.
