How to add UserRoles into the user table [Angular UI]

I am trying to have UserRoles shown as badges next to the UserName in the users table using a PropContributor.

Could I use the getRoles(data.record.id) api from IdentityUserService here somehow? Thanks!

export function userNamePropContributor(propList: EntityPropList<IdentityUserDto>) {
  const droppedNode = propList.dropByIndex(0);
  const userNameProp = new EntityProp<IdentityUserDto>({
    ...droppedNode.value,
    valueResolver: data => {
      const roles = // getRoles(data.record.id) api from IdentityUserService??
      return of(data.record.userName + roles);
    },
  });
  propList.addByIndex(userNameProp, 0);
}

Solved with:

const service = data.getInjected(IdentityUserService);
