[help request] Google assistant CURL command

[switey]

hello, I'm using curl to communicate with my tv.
I was looking at your code and I found lines responsible for sending a request to google assistant to switch inputs (hdmi1/2/etc).
my efforts in translating python (zero knowledge of this language, im a total amateur, know only basics of java) into a working curl command turned out to be a failure.
could you possibly help me in formulating a curl request that would accomplish switching inputs?
