(world is in 1.13, but you should be able to join in any higher version without any complications)

In 1.13 the observers could be trigered by a fire charge, this no longer works in higher versions, hence the torches.
Upon arrival the elevator doors open automatically and close after a short moment. The doors can again be opened from the outside using the button or from the inside using the observer. The doors will then remain in that position (closed or opened).
If the elevator moves to a different level the doors close automatically in case they are not closed already.
You can call the elevator from any level to your level. Unfortunately the elevator will stop on every level for a moment and from the inside you can only go one floor up or down at a time, so you have to activate the observer again and again to go to the next floor.

Newer improved version, doesn´t stop on every level, noteblock instead of torches:    • Minecraft Hyper Realistic Elevator 1.21
