Some hatch mechanics 📐🔨

I am often a DIY’er and I have a really heavy hatch (32 kg) at home that I want to open automatically with an electric actuator. Something like the hatch in the image below. You can buy these actuators for 50 to 100 euros online: but which one do I need? or: What is the minimal and maximal length (and stroke) that I need? What is the force the actuator should be able to push?...
