On the Application Overview, click on Copy CURL to Clipboard in order to copy the executable command to upload the app.
The CURL will have a format like this:
After copying the CURL, head over to TeamCity.

Select Command Line as the Runner type.
Select Command Line as the Runner type
After that, you can paste the CURL to the field Custom script.
