How to Unmount an Exernal Drive using KM

I use TheBrain on an external drive because my MacBook Air’s internal drive is not large enough to hold all the attachments. Upon occasion, I have unplugged the drive before the program has completely Quit. I would like to make a macro that quits the program and then automatically unmounts the drive, but can’t seem to find a KM command that will unmount a drive. Is there one that I’m missing? Thanks.
