I can't install the widget on Samsung Smart TV 2015

Hello! I have a SMART TV Samsung UE40SV6450 from 2015. A few years ago I installed a widget on it. At the same time I used Tizen Studio 4.1.1 which included TV Extensions-6.0. Now I want to install another widget. I installed Tizen Studio 4.1.1 and found that it comes with TV Extensions-7.0. I was unable to install the widget with Tizen Studio 4.1.1 and TV Extensions-7.0. I think it’s a matter of the Extensions version. Tell me how can I install Tizen Studio 4.1.1 with TV Extensions-6.0.

You probably are using something not supported on the Tizen 2.3 version
See this General Specifications

I know it can be done but I don’t know how to do it. If you still are stumped on Monday let me know and I’ll see if I can find some documentation.
