realm apply where clause to the innerRealm list

I have a realm object mySchool which contains a realm list of class myClass which contains a realmlist of myStudents.

    myschool{
             realmsList<myClass>{
                                 realmList<myStudests>{
                                                       bool isPresent
                                                      }
                                 }
             }

something like this.

now I need to fetch the schools with a list of classes with present students.

I need to filter out the students who are not present. and the class with no students.

I tried where("myClass.myStudent.ispresent",true) but it dosen't work.

is it possible to filter sublist in realm? How do I create such a list in realm?
