Notification when Nitro from events is about to run out

Hello!

I have gotten one month of Nitro for free by an Opera GX event. Instead of just being one month and done, discord added me to its subscription. To my shock, one-month later, I got charged nitro pro (9.85 Euros/ month) and used my one time refund to get my money back.

My recommendation: Give people who have gotten Nitro by an Event/ free trial an Email or notification that their free trial / subscription is about to run out, so that people can decide if they want to continue with the normal rate and pay or unsubscribe from the subscription and be done with it.
