HELP NEEDED: SPLINE AND WORDPRESS INTEGRATION

Hi my goal is to create a single page website on spline and wordpress without webflow or framer.
Currently I am trying to rotate a Macbook 3D model using scroll animation. But the problem arises when there is nothing to scroll on the website except the embed.
How should I go about it. Is there any way through html that I direct all the actions on the website directly to the embed.

Please help if possible
