WebSocket Response, write to server/client

[Amiflon]

Description

Add an input field to the Response window, WebSocket tab, from which you can send data to the server or client while the connection is active. I often work with WebSockets and I miss this feature.

Why this feature/change is important?

This will take Proxyman to the next level without having to use other software, such as Insomnia.

May I ask:

• Do you know what app allows you to write a new WS/WSS during the interception?

Insomnia/Postman is different because they make a WS/WSS Connection, so it's important to be able to write the WS Message.

They write that "whistle" also has this feature, but I need to check it:

Ah, it's allowed you to repeat the WS/WSS and send a new message.

It's different what you initially mentioned that you'd like to add new WS Message during the interception.
