Filter with link table json field

I've table call students and it has a link field called class to table called classes.
Normally I can filter without any problems using like this,

xata.db.classes.filter({ "grade->v1" : 13 " }).getAll()

xata.db.classes.filter({ "grade->v1" : 13 " }).getAll()

How can I filter using student table like that. I tried some of these. But none of them worked.

xata.db.students.filter({ "class.grade->v1" : 13 " }).getAll()

xata.db.students.filter({ "class.grade->v1" : 13 " }).getAll()

xata.db.students.filter({ "class->grade->v1" : 13 " }).getAll()

xata.db.students.filter({ "class->grade->v1" : 13 " }).getAll()

Is it possible to filter from the linked table to json fileds like that?
