Is there any way to access settings/setsystemsettings in lg webos?

I have the 2019 version of lg smart tv(60UM9600PNA).

I want to control my TV using a web socket.

I sent json payload like below.





"payload":{"category":"option","settings":{"country": "USA"}}


However, it fails with the following error.
"401 insufficient permissions"

On the other hand, "uri":"ssap://settings/getSystemSettings" succeeds.

Is there any way to use ssap://settings/setSystemSettings?
