Access Expose on spawn property in C++ after a blueprint construct block


I am currently trying to construct an object in blueprint using a Construct Object block.
This object is described in C++, where I have a property with exposed on spawn set to true.
When using the block, I can assign a value to this property.
However, I am unable to know in which method, in C++, I’m able to use this property set.
In constructer → This property is not set
In PostInitProperties → Property not set
In PostLoad → Property not set

Is there a Post something to signal the end of the BP construct object block process? Or should I use a custom method?

Thanks !
