Confused about UE5 products on FAB

I am a bit confused regarding the content under the UE5 tab on FAB.

I recently released a 3d model of a pistol on FAB. It is a static mesh (with textures and materials), but with no animations. I did get approved and went live on FAB. However it was only findable under the tab “Products”, If I went to the UE5 tab it could not be found.

I realized you need an UE5 format for it to be available under that tab, so I assumed that meant ue.asset. After some research I came to the conclusion that you have to send an entire project with the listed asset in the content folder. I’ve send it in a few times but it got rejected all times (different reasons every time). The last time I got the feedback that all firearms need to be rigged and animated.

Now I’m just confused if I misunderstood the UE5 format? Is this for uploading single assets? Why does my gun need to be animated in UE5 format but not in fbx format under the “Products” tab?
I wanted it to be available under the UE5 tab as well for more exposure to costumers, but I’m confused what the purpose of the UE5 format is?

I had one of my products labelled as Mature and was difficult to find… the reason was that is was marked Mature, because the Asset Pack, In The Kitchen, had one mesh called ‘Whiskey Glass’…

I had it changed back, when I pointed out that both mine and 99% of other Kitchen assets, all had knives in them… It is worth looking that it is in the right category of Mature or not.
