Jamming Feature Request: How to start preview track

Hello everyone! I would like to know if I am overthinking, I am doing the jamming feature request project and I am torn on how to begin. I am wondering if I should add a folder called TrackPreview and add a JS and CSS file and add it to my SearchBar.js file or if there was a way using the Spotify SDK to add preview track to my project. If anyone has any tips, I would greatly appreciate it, since I have been driving myself nuts on which way to go with my project.

Here is the link to my project:

Thank you!
