What is the significance of storing a JSON Web Token (JWT) in memory, and what is the process of accomplishing this

Learning about JWTs has been quite the journey. People keep emphasizing not to store it in cookies or local storage, which makes sense. But hearing that I should store it in memory just leaves me scratching my head.

Imagine making a fetch request with JavaScript to my Express server and getting the JWT accessToken in the response. What do I do next? How should I securely store it and pass it along with my subsequent requests?
