Is there a function as easy as this where the permision could be granted for a user upon purchasing a package in Tebex and then expire after one use.
Tebex has the option to allow one minute used but the PERMISION Calltome   which is similar to the oxide helitome or global.drop would be awesome.

Trying to mess with the plugin to allow similar but always seems to allow the user to Callheli (USERNAME) to anyone and not just themselves.

Perhaps I'm missing something here?

Just want the player to purchase a one time use in game if they want to take down the heli at their heli tower

I have tried everything but cannot isolate a heli call to just that one player,  it's like there maybe should have a chat command of /callheliself  or /callhelitome  or  /callheli (USERNAME)  the latter being restricted to self
