My Eufy 2K battery door bell is missing Halloween themes again this year. Is there a way to get it installed?

Last year the doorbell needed a f/w update to get the Halloween doorbell sounds installed.
It worked for approx. 1 week and then the sounds were removed automatically!
trying to get them back …
Does anyone have any hints or tricks please?

Idk my doorbell hasnt worked correctly today , it was working and now its offline.
