Resume only one thread when debugging in Pycharm

A normal workflow I have when running a test that runs an app in another thread is to have a breakpoint at the end of the test and then  pause / resume the other thread.

So, I can have two threads: the main one stopped in a breakpoint inside a test, and the other one stoped in the breakpoint I want to check. Unfortunately, when I resume a breakpoint in one of the threads, all breakpoints resume at the same time —involuntarily finishing the test.

I am looking for how to resume only one thread, instead of all of them.

Thank you! :-)
