This is a one-to-one replica of the ender relay concept a youtuber by the name of Kenadian made.
The resources for the block were provided by Kenadian.
The Ender Relay is a block that can only be used in the end, it is crafted with a lodestone compass and can be charged like a respawn anchor, instead with a end crystal. When a player clicks the block, it teleports to the lodestone compasses location, ontop of the lodestone.
This completes the trilogy of the bed, respawn anchor by introducing a transportation item for the end dimension.
For more on the concept (and the mod, since its a 1:1), watch the video linked above!
