How to connect the Somfy RS100io roller shutter button, end control

Hello.
I have external roller shutters with Somfy RS100io Hybrid motors. The motor has both remote and push button control.
However, I have some doubts about the push button control.
If I connect the button to the roller shutters 1-0-2 and switch it to, say, 1, will the roller shutter go all the way down and disengage the limit switch.... assuming the button is not released at 0, what will happen ? will the roller shutter operate from the remote control ? or will it be locked all the time ?
It is also possible to use roller shutter buttons such as bell buttons, but then you have to hold the button until the roller shutter closes/opens, is it possible to do some kind of hold until e.g. the moment it is fully open (i.e. until the limit switch) ?

Relay short-circuited by a bell switch and open-circuited by a cut-off in the power supply circuit.
