There are 4 datapacks adding teleportation triggers.

Home

/trigger sethome will mark your home location and /tigger home will teleport you there.

Spawn

/tigger spawn will teleport you to spawn.

TPA (Teleport Player to Another)

/tigger tpa set <player id> will send a request to the player. That player can then use /trigger tpaccept to allow the teleportation or /trigger tpdeny to deny the request.

The player id can be found on the player list next to each players name.

Back

/trigger back will teleport you to the last location you teleported from.
