Minecraft 1.14 control Lama with wasd?

There's the possibility with motion and so lamas with wasd to control. How can I do that best? Try it now forever. So you have to somehow get your own motion on the lama and that's my problem
I play on the 1.14.4

That's not possible, llamas are there to transport. You can hang there chests and pull the lama with a leash (like an extra inventory) but you can't ride the lamas properly… Only horses and donkeys can be ridden.
