Getting a .fbx Asset to play a sound through WWise when wanting to interact with it

Hey There!

I have a .fbx Asset and wanted to apply all the things listed in this tutorial: https://youtu.be/mZCP7xexdtw
I encountered 2 Problems with this, first problem is, when creating the actor Blueprint for the chest, I couldn’t find the skeletal mesh I imported to add as a component, therefore no interaction can happen. secind thing is, I couldn’t add the event interact for the chest blueprint. I am Using UE 5.3 for your understanding.
Hope you can help me, cause this is a study project and I gotta finish it ^^
