That's actually mostly handled in the later game tutorials,
#30-33 show topics that are usefull in real time battles, e.g. combatant spawners, move AI, damage dealers/zones, etc.
As set up in the tutorial, you'll most likely want to use a
Real Time Battle Area instead of placed battles and use combatant spawners to have the combatants in the scene, running around (via move AI) and attacking/hunting the player.
How enemies behave is handled by their battle AI, e.g. the game tutorial set up the AI for the supporter (I think) to use boost if the status effect isn't applied, so that'll most likely be the first action. That's up to you how you want to set it up.
Real time battles also use the combatant's
Timeout setting (in the combatant's
Battle Settings > AI Settings), which determines the time between using 2 actions to prevent spamming the ability back to back.
