Keycloak 20.0.0 admin console

Hi Team!

I am trying to integrate keycloak 20.0.0 as an embedded application with Spring boot. When I run the application and open admin console page, I am getting this error

Caused by: freemarker.template.TemplateNotFoundException: Template not found for name "index.ftl".

On investigating further, I found out that admin theme is not being added as a library in this version but it was fine with 18.0.0.

Can anybody help me with this?
