3D FPS to 2D mouse

Alright so I have this game where in the first scene the player is a first person camera that moves with WASD and looks around with the mouse. When I exit the scene, There is a 2D, flat canvas where the player clicks a button and the game continues, but the mouse isn’t appearing on the 2D scene. I know it has something to do with the mouse being used to look around on the first scene but I don’t know how to fix it. I need to get this game done as soon as possible so any responses help!

Try setting the cursor. Add this to a script in the menu scene.

void Start() {
    Cursor.lockState = CursorLockMode.None;
    Cursor.visible = true;

Scripting API: Cursor

Scripting API: Cursor.lockState
