Sometimes you have to wait few hours to have it visible.
I upload my project in forums.unreal.released-projects this page but I couldn’t find my post on the list !!

as you can see it says it posted in the released project section
I post it more than 24 hours ago.
Thanks ego for your help.
I can’t find it on forum neither. Maybe you can try to contact UE support.
