How to migrate from Lastpass Authenticator to bitwarden?

I root my android device and pull Lastpass’s database to my pc.

/data/data/com.lastpass.authenticator/databases/databases
/data/data/com.lastpass.authenticator/shared_prefs/LMIAuthenticator.xml

But it seems secret keys in the database are encrypted. Does any one know how to decrypt them?

I have enabled 2FA on about 10 sites. I really dont want to reconfigure them one by one on each site.
