I´m having trouble to execute an function from a parent actor in it child inside the level blueprint

Hi, I´m having trouble to execute an function from a parent actor in it child inside the level blueprint. I just want the specific child to glow.
I’ll post some pictures to elucidate more and because i can´t explain in a clear way in text.

“Osso_alterado” is the actor that contains an actor named curva_c which is a child from Teste. Teste is the actor that has the function that i want to use.

this is and print from inside “Osso_alterado” just showing how Teste and Curva_C are connected

This last print is just showing how i made something similar and it worked. When the player hits the actor with the cursor the actor glows.
The thing is, i don´t know what i have to connect on “object” inside the “cast to Teste” for this to workout

Between Cast and get CurvaC you need a “Get Child Actor” Node.
