do you have a sample project use this AgoraChat-CallKit-android

[lujia-zhai]

I had created a video calling demo project. And want to add a call invitation use this AgoraChat-CallKit-android sdk,
but even I read this README, i still not understand where and which file to insert [Initialize AgoraChatCallKit] and [Send a call invitation] and how to run these.
Could you update a step by step document or whole runnable demo project?

OK, we'll tweak the readme file to make it look friendlier。The example project link is at the bottom of the readme。
