Not sure you are still interested, but I found a solution that is somewhat acceptable:

Create a file with this in it:
21#:MSFEXPLORE \Windows\Start Menu\Programs\Games
and name it Games.lnk or something

Put that in \Windows\Start Menu\
and you should be able to put that on the TF3D start menu

What this does is go through File Explorer straight to the Games folder
Sometimes it wouldn't work for me strangely (as in nothing launches), but lately it hasn't failed

Attached the exact .lnk that worked on my phone
