I can help you out! These seeds are really easy to harvest. Just cut the fruit open, remove seeds, and let them sit and dry for 24 hours. Place them in a general purpose potting mix on their side, and moisten the soil. Do not get the soil very wet, and do not let it dry out. They will want it in between at all times. Almost all of them will sprout.
Unless you are in a tropical environment, you will want to keep these as houseplants. They can tolerate bright light, but they prefer filtered light, or partial shade.
Keep dolomitic lime in your soil to keep the pH stable, as they can be a little sensitive to change.
They are susceptible to many insect pests. I have a mix that I recommend. It is as follows: First, you will want to prime the soil with dolomitic lime, then spread wettable sulfur to Kill off any infection in the soil. I Also like to spray the plant itself. Mix a few drops of one or more of these ingredients into warm water with a spoonful of coconut oil: Rosemary oil, lavender oil, neem oil, garlic oil, cinnamon extract/oil and for really bad cases, also add clove oil.
