I accidentally Skipped Backup phrase for win-10

As in title , just after installing raven-coin on my windows 10 , i had accidently skipped backup phrase portion while dumb me was step by step copying youtuber steps. i have just today installed it. When i uninstalled the ravencoin wallet and reinstalled it, there was no option asking me for backup phrase. what should i do ?

this was something i noticed when the Wallet adress kept on changing for each button of "RECEIVE", i clicked. I am Brand New to this.
