Get transform of component from spawn actor

Hi, i’m working on a level blueprint to spawn actors “parts of level made inside blueprints”.
Those parts have Arrow components to know the start point and the end point of the blueprint mesh in order to spawn others on the end of others entrances to make a custom thematic map.
The problem i have at the moment is if I make a function in the level blueprint in ordr to make it easy to work or make it work random i cant get acces to the spawned actor Arrow component.
How sould i proced in orther to acces the component of the actor ?

Hi, same problem here and the only similar post i found was this but with no answers :frowning:
