While I think that's the most "obvious" solution and can be verified
by inspection: there's only out input state that is "false", so write an expression
for that one state and invert it.

However, you can apply De Morgan's law to simplify it:

       not ((not BotWaitForCooldown) and CooldownDetected)
       
is same as

       (BotWaitForCooldown or (not CooldownDetected))
