is there a way to make the bot follow me on command

[tk746]

Ex: !follow and it would follow the player that sent the message (if they were in render distance)

Or is there a way to make the bot say a message when someone joins the server?

or a way to make the bot automatically reconnect if it crashes?

thank you!

Look at the example in mineflayer-pathfinder
