Making a Horror game

Hi there , i am completely new to unreal engine when it comes to making games so i might need some help with a few issues . i started a project of a first person horror game before 10 days and it has been going smoothly , but i didn’t know that i needed the hand that comes with the blueprint ’ BP_FirstPersonCharacter ’ to make some animations like driving a car or picking up an object etc… , i tried to extract the body of a Metahuman and implement it in the ’ BP_FirstPersonCharacter ’ but it just didn’t work , cuz when i play the game the Metahuman body is still visible and i cant see the body in the viewport , i tried to fix it at least 5 times but it just didn’t work , so can someone please help me ? , also i have this idea of making a flash light pointing at option that the user hover on in the main menu , is it possible to do it with basic coding like HTML,CSS,JS etc…? if not can someone tell me how to do it ? i would appreciate it .
