Want to escalate ground politics to CEO

Six months back I started working on AI based project which is an R&d from scratch when I completed stage one New people who are higher position than me started working with me to extend it to next phase I felt very happy but the things didn't happened in expected way. I thought they came to me to coloborate and help the project but I came to know at some point that they are just here to showcase the work I did, prepare ppts to explain clients. Moreover project manager showed favouritism by giving liberal tasks or already completed tasks which don't need any research to be done. I didnt focused on this because my focus is learning. I have completed phase 2 on my own which is converting to project, and when I completed it they started asking me to share code and provide KT this made me suspicious, So I didn't shared the code, dragged it for 2 months they tried to achieve by their own it didn't succeed for them so again they started asking me to share knowledge. I know if I share the code and give KT, I will be thrown out from this. They started ghosting me by doing prank calls like whether I am looking for an oppurtunity outside. After some days I decided this not my place to work, my focus should be on skills and solving problems with these politics in my initial stage of tech will not going to help in long run. So I shared and provided KT then next day I am released from the project. After few months I am asked to force resign because of being on bench.

I thinking to share these things to my CEO, along with proofs it upto them to take any action or not. The same thing happened to my colleague in another project. I don't want this to repeat for others.

Need your suggestion on this. Company persistent systems private limited.
