Two Button detect for long press same time

Hi all,

I have on a panel two capacitive buttons, Fan (three steps) and Light control (three steps)

Short press -> Fan step_1, press -> Step_2 press -> Step_3. Same with te Light button.

But, I try to make a config setting with these two buttons.

If hold the two buttons on the same time for 5 sec down, jump to the menu.

Any advice for this? making for each button a LoopTime to detect long or short press?
