Click Actor Through Render Target

Hi guys.

I’m building a full-3D Inventory.
When the player wants to open the inventory, an “InventoryActor” is spawned that visualizes the Inventory.

This Actor produces a render target. This RenderTarget is used within a Widget as an image.
I’d now like to click on my items in this Inventory. Is there a possibility to project a click on the Image to the Separate Inventory Actor?
