How to add Volume using Kitematic?

Hello Team,

I am new to docker and Kitematic UI. I have just cloned and configured Magetno 2 [1] on my Mac. I want to access the files inside this container on my host (Mac) machine. I am looking around for solutions and not finding any. The settings in Katematic is not showing any option to add a new volume for this container. I would like edit the files via my IDE installed on my host machine.

Any help shared will be helpful.
