Where is BPM Screen?

Hi… I just bought CUBA Platform Full. And I was going to use the BPM component.
But the documentation says:
Open the screen BPM ? Process models in the running application web interface and press Create. Enter the model name Contract approval and press OK. A new browser tab Model editor will be opened.

Now, where’s this screen BPM? Was it in the studio? Or should I download any other tools? I have IntelliJ IDEA with me.

Sorry… Really my bad.
I just realized it has to be done in running web application.
