If the field is static, you need the pointer to the class' static fields (il2cpp_class_get_static_field_data), then simply add the field offset to it, then readInt or whatever. Otherwise, use the object pointer instead.

if the field is not static? I learned to edit using the name, but I didn't find anything about going by his offset, how to do it by offset? using class object

This is how I do it: https://github.com/vfsfitvnm/frida-il2cpp-bridge/blob/3754f1e9ee77eadede4953e11bb647cb0a2ec025/src/il2cpp/structs/field.ts#L117
