How to teleport my player character from anywhere?

So I’ve been trying to learn how to use unreal for a project of mine, I’m attempting to
make a mechanic that allows the player to TP exactly -100Z from where they currently are via key press.

Same X, Same Y, different Z
Same rotations

However I can’t find a way to actually apply this, I’m sure its incredibly simple but its nowhere to be found.
Ideally I want the player to go back up but I can just replicate how to go down.

Basically can anyone inform me how I can press a button to make the player to -100Z down
Bonus points if you can also help me get the player character back up the same way.
