Button Type don't work

I have a very big problem.

I have make an product with an shelly UNI but the Button Type don't work, exactly always behaves like a toggle switch.

I would like a "Detached" button, separated from the relay and that works in momentary mode, like an pushbottom.

This doesn't work on shelly uni, and all settings in button type always behave like a toggle switch.

How can I do?

I want out 2 to work this way

any settings on OUT 2 about my shelly UNI

behaves as if this setting were set

I want that when I press the button on output 2 there is only one pulse. And I want this button not to be conditioned by input 2, but to be free, detached from IN 2.

As for the schematic it is not important, but if you really want to know then let's say that I use a multimeter in resistance mode and I watch when the optocoupler is on or off

I would also like to know if it is possible to implement a button type with short pulse for switching on and long pulse for switching off of my equipment, or better it would be possible to set the duration of the two pulses ON and OFF, so it would be very generic
