Is it possible to filter over nested objects on stream-chat?

stream-chat v6.7.3

When I connect a user besides id, name, and image, I'm adding my own properties as an object, like this:

await client.connectUser({
            id: 'jose',
            name: 'pepe',
            image:'https://i.imgur.com/YEGTFwf.jpeg',
            myObject:{
                'id':1,
                'categoria':'writer'
            }
        },
        client.devToken('jose'));

but then when I try to query the user it simply returns an empty array, I'm trying like this:

await client.queryUsers({"myObject.categoria":"writer"});

I have tried over id, or other properties inside the user object and the filter works like a charm, so I'm wondering if this is the right way to do the query. Or if is it possible to query over an inside object.

According to stream support, "Currently the API can't filter over nested objects like this, only values in the top level."
