Connect using proxy url like "wss://app.company.com/mqtt"

How can we connect (only) using the proxy url like "wss://app.company.com/mqtt". We created a proxy url that points to mqtt broker for websocket listener from ingress on kubernetes. From **paho-javascript** library we are able to connect using a single fully qualified WebSocket URI like this "wss://app.company.com/mqtt" on the constructor. I am asking for the similar behaviour.
