how to subscribe to an event in blueprint

[Amaratsu]

Hello, how to subscribe to an event in the blueprint, I don’t need to send anything, just subscribe to the alarm from the signalr side, I noticed that there is a signalrwrapper, but I didn’t understand how to interact with it, I will be glad for any help

I see example from readme for C++: Hub->On(TEXT("EventName")).BindLambda([](const TArray& Arguments)
{
...
});
but not blueprints
