When I try to send "SendCommand", I m faced on the error of Websocket_Error cause of HTTP/1.1 403 Forbidden.

Hey, there is a new way: add --remote-allow-origins=* to Chrome's launch options and restart. It works like before without changing the library.
I found it here: https://youtrack.jetbrains.com/issue/WEB-59211/Cant-attach-debugger-to-Chrome-Dev-111-Invalid-handshake-response-getStatus-403-Forbidden

Edit:
You can launch chrome like &"C:\Program Files\Google\Chrome\Application\chrome.exe" --remote-debugging-port=2229 --enable-logging=stdout and connect, you will get an error like

[30040:29896:0408/182416.107:ERROR:devtools_http_handler.cc(766)] Rejected an incoming WebSocket connection from the ws://127.0.0.1:2229 origin. Use the command line flag --remote-allow-origins=ws://127.0.0.1:2229 to allow connections from this origin or --remote-allow-origins=* to allow all origins.

then set options to --remote-allow-origins=ws://127.0.0.1:2229 for better security(maybe)
