Stripe Problem - Expired date

I thank all of you in advance and I apologize for the rough English I use. Forgive me.

What I would like to create is this:

When the user subscribes to a plan, his status becomes “VIP” at the end of the subscription, I would like his status to become “USER”.

What I have done is to create a db that registers the new “VIP” status when the user automatically subscribes. I would like to understand how to automatically implement that the same status, at the end of the subscription, becomes “USER”.

I am new and I have recently implemented stripe, I tried to search on the forum but I could not find what I need. I hope you can help me, I await your expert advice. :slight_smile:
