[keycloak-user] Mapping claims and assertions from second identity provide

Hi I am trying to map assertions from 2 identity providers. I have users who need to log in using their gmail accounts, but I would like to allow them to have a "verified" github account linked to it. I get the users names, emails and other info straight from google and need their github login name from github. I have successfully linked both identity providers, but the assertion mapping only happens for whichever identity provider I use to first create the account. If i use github first I get the github username and if I use gmail I get the details from there. What I would like is for the mapper to run for both identity providers. Is there a way to run mappers from each identity provider as it is added to a user profile? Thanks
