In this case it is useless that I store the access_token if I understand correctly, I just need to store the refresh_token and ask, each time I start my program, a refresh to use directly and dynamically the access_token provided which changes each time my program starts?

It’s up to you. I store both and validate the token(s) at boot and choose to refresh if the token has < 30 minutes left on it
