Since it is a "push to open" type latch, if you have an accumulation of ice under that is thick enough to prevent movement, then you will/may not be able to disengage until it thaws. Maybe take a hair dryer to it before leaving home to ensure it opens.
I had my 2018 Equinox fuel door freeze shut one time.
My garage was warm enough to melt the ice and I was able to open the door.
When I was the car in the winter I dry the inside of the doors and hatch so they don't freeze shut.
I now dry the inside of the fuel door.
