[serenity404-gha]

These changes are linked to SPHR-12342 and SPHR-12343 and are based on the designs here https://wiki.corp.adobe.com/pages/viewpage.action?spaceKey=MKTOENG&title=XDM+Design+for+Sales+Owner+Project.
The field group XDM Business Account Details will be modified to add accountOwnerID.
In addition, two new classes will be added:
B2B Account Team, which will link the accountOwnerID to one or more B2B Sales Users.
B2B Sales User, which will provide contact information about the sales owner.
