Paper Tpa

So well I made this PaperMC plugin for 1.21.11
it adds:
/tpa (player) -> you requested teleport to (player)
(player) sees: (player) requested to teleport to you. Do /tpaccept or /tpdeny
if you try to teleport to yourself: you cannot teleport to yourself

/tpaccept -> accepts player teleportation
/tpdeny -> denys player teleportation

/tpa requests expire after 2 minutes
