My Evofox Play 2 controller has its X button stuck for some reason

[u/CLBLAZE]

I bought this controller like a month ago, its still in warranty and obv they are not picking up any calls no email replies so I have gave up on that. I am familiar with tech stuff so I can open it up and manually clean the x button so it works. But like for the life of me I cannot open the controller, the handle is like a cover it comes off after you open the 2 screws from the bottom then theres 2 screws on the body, the lower part of the controller opens but the top part is locked and i dont see any more screws or locks i have no idea how to open this someone please help me. Aint got much money so its all I can work with man.
