Bluetti bucks expiring

Hi, I got a notification that I have some Bluetti Bucks expiring and I have to do one of the “available actions” to extend them. But I can’t figure out what the available actions are. Is this info anywhere? It looks like I have around 2400 points (2000 signup plus a purchase I made a year ago). Is that enough to care about? I was also supposed to get double or triple points for the purchase (Elite 100v2) but I only got single points, no idea if I should care about that either.

Any suggestions what to do with the points? I don’t need another power station right now but maybe there are some useful accessories.
