Install my app forever without using store - no development mode - just on my TV

Hello, is there any way how to install my app to my own LG TV without using store - no development mode - it means for ever??? I want to have my application (developed by me) in my TV for my purposes - some info/commands from/to my home automation control system.

You can install webOS TV apps only from the LG Content Store. Sorry for not being helpful.

is it possible to install the apps forever with dev mode on? im using vscode plugins to install apps

As the Developer Mode app is for app testing, it has some limitations; you cannot use it for permanent use of your app.
