Car won't move forward or backward in the driveway due to being stuck in snow ~ What's the solution?

I backed the car out and then it got stuck. It’s right near the street. I got out, shoveled in front and behind all four tires, put cat litter in front and behind front tires for traction. I have turned the steering wheel in all directions, put the car in Drive 1 and 2, put it in reverse, does not move. Front tires are spinning and at this point they seem to have made an icy clay out of the cat litter.

I called the neighbor to see if they’re available to come give it a push, or I’ll push it if they will drive. In the meantime, or if the neighbors are not available, is there a solution?
