How to get player's UUID and return it into Head texture?

Hello guys! I wanna make an item display with head model in my world which will get texture from random player's head. Pls don't ask why I need this...  I bought Minecraft license key and I have a microsoft account, so it's not a problem of pirated accounts UUID's...

Here my command (it doesn't work how it should works, it just turn Steve's head into Alex's head):
execute store result entity @e[tag=test,limit=1] item.components.profile.id long 128 run data get entity @r UUID
