Nano every controlling MKR relay protoshield : is it possible ?

i try to control a lamp with my arduino nano every and a mkr relay proto shield.
I have read that nao is compatible with every boards.
But i’m wondering as now i can’t put my relay output on or off.
The mkr receive information from the nano every board the pin 1 that command relay1 receive on & off order.
But there is no output on the lamp.
Is there something i’m missing.
For now i have only made test with a 12v lamp, and the nano is connected to the shield with only wires, no transistor or led or something.
Id somebody can help me on the compatibility of the 2 boards, thanks a lot.
