How can I make the scene change appear in a certain position that I want in the scene, I have a map and I want it to take me to a part of the map as next to an object when the level is finished, instead of showing the position that you are in character on the map, can you send me what the events would be like?

You cannot display two scenes at the same time, but you can hide and show layers to display a menu or a map, if you want.
