When to refresh a JWT token?

Currently I am using JWT-Auth on my Laravel back-end to protect my API routes with a token. However, after a certain time the token gets invalid and I get the error 401 Unauthorized. So I guess I have to refresh the token somewhere. When would be the best time to do this? I read about doing it every time you make a request but I want to be sure that’s the right way to do so. I used this guide from their docs: https://jwt-auth.readthedocs.io/en/develop/quick-start/#create-the-authcontroller. In here they make a function to fresh a token. But how would I implement this every time I make a request? Do I just call this function in the controller with an Axios request or call it in another controller or something? Any tips are greatly appreciated.

I have a Vue.js front-end by the way.
