Setup emulators with Intellij

Is there an instruction on how to setup emulators with Intellij? 

Above is what I see for Android Studio vs Intellij. Each time I start the project in Intellij, the emulators are missing and I am not able to find a consistent way of connecting Intellij to the emulators. I can start the iOS emulator by "open -a Simulator" in Terminal. The emulator opens, but it's still missing from my Intellij project. With android, it's the same way. I can start the emulator and it's still missing from my Intellij.

Run/Debug configurations > + Android App > Deployment Target Options > Emulator bring up an option to select the Prefered Android Virtual Device, but I'm not able to browse to point to a device. The button to browse is not responsive.

Strangely, if I keep the Intellij IDE open for a while the target device option sometimes shows up. However each time I close and open the Intellij IDE, the target device option goes away again. 

I did do a google search and the results doesn't point to a consistent solution or instruction, below are a couple of examples.

I'm on MacOS 10.14.6 and using Intellij CE 2019.1.2.
