It'd be nice to get WSS support for the app! Postman unfortunately doesn't have this but that dont mean POSTWOMAN cant 😈

I got my eyes on this feature 🔥✌️

Oh yes!! This feature would be so useful for me. I do a lot of work with websockets and I have nowhere to go to work with them.
@liyasthomas feel free to assign me and I'll get working on this immediately!
