You don't see minor 69 chords often in chord charts or songs, it is an interesting sounding chord so that doesn't mean you can't use it. You can play minor 69 chords in place of any chord that's functioning as a I chord in minor keys or a ii chord in major keys, but you could try playing this minor69 inversion in place of any regular minor chord and listening to how it sounds. If it works, use it!
