SystemControl API

I have a problem with Samsung signage SystemControl API(SystemControl API | Samsung Developers). When I call any function from this API, I am receiving SecurityError “You do not have the privilege”.
I use Samsung signage TV with Tizen 6.5.

Please advise!

Since no one responded, I would suggest you look for an answer in the FAQ-Q/A under the most appropriate topic on the Smart TV Seller Office site If you don’t find a solution there then sign in and open a Smart TV Seller Support Request . They can help you better there.
