Need simple relay control

I am new to Shelly and not sure what device to use.

I need to control a NO relay to control a power window operator.

Window operator has its own power and control, all I need is to close a nonpowered relay and then open it to start the window operation. There are separate relays for window open and window close. With 4 windows I need 8 separate relays.

I am not sure of the timing of the close then open, but guessing that will be adjustable in the shelly script.

I have power available to power the shelly (120V) but power is not coming from the relay wires I need to control.

Plus1 is a single contact, so I would need 8 of them. Is there an option for one with more contacts per device?

The Shelly 1 Mini Gen3 says it is a dry contact, would that work?
