Decrypt received poll options when unvoted

[Ased2235]

They're sha256 hashes of the option names and can't be decrypted. You need to remember the original option names.

https://pkg.go.dev/go.mau.fi/whatsmeow#HashPollOptions can be used to get the hashes from names, but you can also just do it yourself

How can we know which option user unseleted?
