how to upload junit test result file to existing test cycle

1.   As of now every time when we upload the junitresult.xml file into the zephyr scale, it creates a new test cycle. but I want to upload it to the existing test cycle and to a specific folder in the same post-call. which is not happening now.
2.  to customize the test cycle name I am sending the test cycle JSON object along with the junitresultfile.xml but, post-call is ignoring the test cycle JSON object.

below is my request:

1. import json
   import requests
   def upload_result_to_zyphyr():
       headers = {
           'Authorization': 'Bearer Token'
       }
        params = (
           ('projectKey', 'xxx'),
           ('autoCreateTestCases', 'true'),
       )
       payload = {
           "name": "Sanity",
           "description": "Any additional description can be added here.",
           "jiraProjectVersion": 'null',
           "folderId": 1111111,
        }
   
       files = {
           'file': open('junitresult.xml', 'rb'),
    }
       data = {'data': json.dumps(payload)}
       response = requests.post('https://api.zephyrscale.smartbear.com/v2/automations/executions/junit', headers=headers,params=params, data=data, files=files)
       print(response.content)
   
   
   upload_result_to_zyphyr()

Response:

I am getting a successful response with 200 OK and the result file is getting uploaded into the test cycle but, test cycle customization is not working.

Any suggestion on the above-mentioned points will be really appreciable.
