name is not any property on a player

#

you can do a tag, team, advancement etc. check

#

an advancement with the impossible trigger can also be used.

#

you can't check the players name, you can retrieve their UUID from: https://mcuuid.net/

Minecraft UUID and username lookup. Resolve, convert and view name history of any username/UUID today.

#

you can use this tool to convert the hexadecimal string to a UUID array:

ah so im guessing no clean 'type and leave' solution
its a hidden advancement so I just reward a function that checks for a player name
