How to send a request to teleport to someone in minecraft?

I'm on this creative server and i want to send a request to teleport to someone.
I tried to to
/tpa (myname) (friendsname)
but it just sends a request to myself. And i can't use /tp because then it says i don't have access
I want to teleport to them, not them telelprt to me

/tpa (friends name)

the server also needs essentials installed

/tp is an opped only command, since the other player dosent need to "agree" with the teleport
