LG WebOS integration doesn't show TV on Google Home/Alexa


I just bought a LG OLED55C2PSA TV, and as soon as I turned it on and plugged it in the local network HA asked to set up the LG WebOS TV integration, which worked fine for the HA. I can turn it on (WOL), off, switch input channels, change the volume. But the thing is, the TV won’t show on the Google Home app, nor the Alexa app, so I cant control the TV with assistant’s voice commands. Everything else shows up normally. Also I subscribe to the Nabucasa subscription and never had any problem getting devices to show up on the assistants.

I found this 2020 issue and it seems that the TV should appear on Google Home naturally after using the LG WebOS integration.

Can someone help me fix this?
