I have a side question that may be related

Is there a way to customize the search?  I thought i was having the same issue since my WIN 11 reinstall i went to load up a game "hearthstone" to play and it did not show up under search, then i went to the start menu-> All Apps and it didnt show there either as a start menu item because i had the game saved on a different hard drive and was using the battlenet launcher to launch it in the past from that directory so windows dosen't know about it ( or it wasnt officially installed right on windows) 

Is there a way to have Start 11 scan for exes in other folders?   

Example I have Battle.net and Steam games I save on a separate NVME and an 8TB Drive under a  D:\Games  for example.

They work fine with the launchers but id like a way to launch them from the start menu.  

Or do i need to just create manual shortcuts to the start menu myself then Start11 will find them?
