How to request 4-band basemaps?

Hello, 

I am trying to figure out how to use either the basemaps api or the orders api to download polygon selections of basemaps. So far, I have this code:
 

 # Order api stuff for basemaps
    def download_basemap(self, session, request, download_location, file_prefix):
        #POST request to get data
        headers = {'content-type': 'application/json'}
        response = session.post(self.ORDERS_API_URL, data=json.dumps(request), headers=headers)
        print(response.json())
        #Construct url for getting request status
        order_id = response.json()['id']
        order_url = self.ORDERS_API_URL + '/' + order_id

        #Check request status, once it's done download data
        while(True):
            r = session.get(order_url)
            response = r.json()
            state = response['state']
            print(state)
            end_states = ['success', 'failed', 'partial']
            if state in end_states:
                break
            time.sleep(10)

        #Download data
        response = session.get(order_url).json()
        mosaic_name = response["products"][0]['mosaic_name']
        coordinates = response["products"][0]['geometry']['coordinates']
        #print("name and coords:", mosaic_name, coordinates)
        #print(json.dumps(response, indent=1))

        #Download each file
        results = response['_links']['results']
        #print(json.dumps(results, indent=1))
        for r in results:
            download_url = r["location"]

            # Save data to file
            # https://stackoverflow.com/questions/37573483/progress-bar-while-download-file-over-http-with-requests
            #print(r["name"], mosaic_name, coordinates)
            download_string_name = r["name"].replace("/", "_")
            filesavepath = str(download_location) + "/" + str(file_prefix) + "_" + str(download_string_name)
            response = session.get(download_url, stream=True)
            total_size_in_bytes = int(response.headers.get('content-length', 0))
            block_size = 1024 #1 Kilobyte?
            print("-Downloading", filesavepath, "-", total_size_in_bytes/1e9, "gb")

            # Download file 1kb at a time
            progress_bar = tqdm.tqdm(total=total_size_in_bytes, unit='iB', unit_scale=True, position=0)
            with open(filesavepath, 'wb') as file:
                for data in response.iter_content(block_size):
                    progress_bar.update(len(data))
                    file.write(data)
            progress_bar.close()

# 3 band data....
basemapRequest = {
   "name": "Basemap order with geometry",
   "source_type": "basemaps",
   "order_type":"full",
   "products": [
      {
         "mosaic_name": "global_monthly_2022_06_mosaic",
         "geometry":{
         "type": "Polygon",
         "coordinates":[[[14.60, 52.30], [14.61, 52.30], [14.61, 52.31], [14.60, 52.31], [14.60, 52.30]]],
         }
      }
   ]
}
API_Wrapper.download_basemap(session, basemapRequest, "../Data/ForestTest8", "testprefix")

However this seems to return a visual basemap (RBG only). I’ve been trying to add fields to the json request like “item_types” and “product_bundle”, but it’s still returning the same visual basemap data. I’m not sure what I’m missing here…
