Winch gemini's safety level do i have to turn up to be appropriate for a roblox game

gemini API have a safety feature especially this one:

in order to make them save, winch Harm category that have to be blocked more?
I know its gonna be the HARM_CATEGORY_SEXUALLY_EXPLICIT and HARM_CATEGORY_HATE_SPEECH that supposed to be the highest.

but i mean, if HARM_CATEGORY_HATE_SPEECH supposed to be too high, what happens if the ai tries to make a joke or being kidding…?
