Word.FieldType.ref support on Word Online

I have an issue in a Word Add-in on Word Online where I'm trying to insert a reference field in insertField method of Range.

I have the same function on Word on Windows, Mac, and Onlineso I need the same result on each environment.

insertField(Word.InsertLocation.end, Word.FieldType.ref, `${bookmarkName} \\w \\h \\t`, true);

I know that Word.FieldType.ref is not supported on Word on Web, but I wanted to ask if there's any ETA on when it will be available or if there's any workaround to achieve the same result as in Desktop?
