How can I pass an argument with websocat without using echo?

[Oroborius]

I am trying to pass a string using websocat inside of streamdeck-linux-gui. Normally in kitty I could do something like this: echo Calibrate | websocat ws://localhost:19190/ which would output and fire successfully. Now the issue is that in this program it executes echo a little bit differently and instead everything after echo gets passed as a string and websocat isn't triggered. Attempting to invoke websocat on it's own works but I cannot for the life of me figure out how to pass a string to it. Any help will be greatly appreciated! :-)

Maybe you want --preamble?

This works! Thanks so much! :-)
