How to set testExecutionKey for Cucumber multipart import using Jira Cloud

[Vera Lankes]

Hey guys, 

I want to import the test results of our UI tests to the referring Jira Test Execution-Ticket using the v2 Cucumber Multipart API (POST /api/v2/import/execution/cucumber/multipart). Authentication and uploading the results is already working; but instead of creating a new Test Execution with the mentioned test results, I'd like to update the already existing one. I tried to set the "testExecutionKey" on various parts of my results.json (following you see my latest attempt), but unfortunately new tickets are created nevertheless.

Can anybody please give me a hint, where to add this piece of information?
Thanks in advance!
