I want to create the custom lead conversion process where user can map the standard fields as well with the objects(Account, Contact, Opportunity) fields. In short I want to override the standard lead conversion process of salesforce along with standard lead mapping functionality.
I have created the LWC component for the same where the user can map the fields. Once after mapping I'm creating the records in the custom object named Lead_Mapping__c. Now how can i achieve the further functionality so that whatever the field mapping is selected in the page should be applied at the time of conversion? Can someone please help?
PS: Hospital is my standard object Account
Below are the screenshots for the page that I have created:
