BB is same as MTB/Road so unscrews anti-clockwise, might not be the same fitment as Shimano or ISIS so you might need to use a different tool, one that is curved with a hook type bit on the end to grip the slots around the outside of the BB
The bearing races should pop out the same as old school, when I took my forks out of mine to get them chromed the bottom race came out under hand pressure but yours might need to be drifted out, only way to know is to take it apart and see
