12V Pulse circuit to operate a double coil latching relay uses no power unless switching

I have this double coil latching relay and I need a circuit that will provide a pulse to switch it on.

After doing the pulse I don’t want it to use any power.

There are two sides to the circuit, one to turn the latching relay and another to turn it off.

I’m using the latching relay as a high voltage disconnect for a 12V LiFePO4 battery.

My BMS has a small 1A 12V relay with NO NC which will provide the power to the pulse circuit that would latch and unlatch the relay.

Thank you
