Question about LG OLED 55ef950v

I did not find the app in the LG Store. However, I found instructions on how to install it on an LG TV on the Internet. Enter the query "how to add plex to LG TV" in Google and the first result I got was "https://www.youtube.com/watch". The installation is explained there. The installation is explained there, the necessary installation file is obtained from "plex.h3consulting.net". I cannot comment on compatibility.
With kind regards
