Saurabh I'm sorry about that. We bought the foodomaa license and we had a lot of difficulties to finish the implementation.
At this point I mentioned, it's about notifications where you integrate Foodomaa with firebase to send push notifications. The guy we hired didn't help us as we expected and most of the solutions we found here on the forum.
I really don't know how to improve the documentation because it's already quite complete, but the point I made is that there are people wanting to sell solutions that already exist.
Sorry about that.
