[Kolla][Keystone] No "Domains" found in identity area.

Hi, I'm using kolla-ansible stable/rocky release to deploy Openstack Try to test with multi-domains requirements. I'm do nothing but add "horizon_keystone_multidomain: True" into globals.yml After deployment, it works because I have to enter the domain name at login screen. Logged in with default domain and admin account. But I cannot found any "Domains" section in identity block. Is there something I miss?
