How to send file via JetBrains REST Clinet?

Question

PyCharm

I use PyCharm and the built-in REST Clinet in my work, I ran into a situation where I need to test the file upload so that the form grabs it.

How many did not fight all one - "the image field in the form is obligatory".

Actually a question how to send a file to the form (in the necessary field)? And in general, is it really possible to do this through the built-in client, or is it better to use third-party applications, if so, which ones (under mac)?
