I am creating custom lead conversion popup window similar to standard one in lightning experience. (There are some requirement because of that I need to create this custom popup).
I am trying to provide same functionality which standard popup has like Create Account with different Name Create contact with different name
etc.
For opportunity, I am able to find a method setOpportunityName in LeadConvert class. But I do not find any method for setting contact and account name upon lead conversion.
Is there any way to update the contact or account name during lead conversion process?
