Cannot connect to LG 65C9

I’m trying to connect met LG OLED with Homey, so I’ve downloaded the LG webOS app to Homey.
When I try to add a device I select LG webOS and Homey starts searching for the TV which he will find.
Unfortunately, the TV refuses the connection.
I’ve tried to search on the TV for a remote control setting which should/could be enabled, but cannot find that.
Is there anyone who can point me in the right direction?

Under Settings - Network - WiFi direct and LG Apps are set to ON? With both on it works for my model.

My model doesn’t have these settings :cry:

What Settings do you have? Is you model connected to your network?
